    BRENDA LYNN SCHILLO,

    v.
    KILOLO KIJAKAZI, ACTING COMMISSIONER OF SOCIAL SECURITY,
    Defendant-Appellee.
    Appeal from the United States District Court
    for the Northern District of New York.
    No. 5:19-cv-00999 — Thérèse Wiley Dancks, Magistrate Judge.
    ARGUED: JANUARY 5, 2022
    DECIDED: APRIL 6, 2022
    AMENDED: APRIL 6, 2022
    Before: JACOBS, RAGGI, and NARDINI, Circuit Judges.
    Plaintiff-Appellant Brenda Lynn Schillo applied for Social
    Security Disability Insurance and Supplemental Security Income
    benefits under the Social Security Act, 
    42 U.S.C. §§ 401
    –434. After a
    hearing, an administrative law judge considered the medical opinions
    of Schillo’s treating physicians as well as other evidence. The
    administrative law judge denied Schillo’s claim, finding that she was
    not disabled under the Social Security Act because she had the
    residual functional capacity to perform her past relevant work as a
    project manager. That decision became the final decision of the
    Commissioner of Social Security. Schillo sought judicial review
    before the United States District Court for the Northern District of
    New York (Thérèse Wiley Dancks, M.J.), and the district court
    affirmed. We AFFIRM because substantial evidence in the record
    supports the ALJ’s assignment of less than controlling weight to the
    opinions of Schillo’s treating physicians about the nature and severity
    of her impairments, and the ALJ’s finding as to Schillo’s residual
    functional capacity. Although the ALJ committed a procedural error
    when applying the treating physician rule, 
    20 C.F.R. § 404.1527
    (c),
    which applies to claims like Schillo’s that were filed before March 27,
    2017, we hold that the error was harmless.

    WILLIAM J. NARDINI, Circuit Judge:
    The Social Security Act, 
    42 U.S.C. §§ 401
    –434, creates a system
    of disability insurance and other benefits for qualifying applicants.
    The task of determining whether an applicant is disabled and
    therefore eligible for benefits is entrusted in the first instance to the
    Social Security Administration (“SSA”). If the agency initially denies
    an application, the claimant is entitled to request a hearing before an
    administrative law judge (“ALJ”).         The ALJ is charged with
    developing the factual record, conducting a non-adversarial
    administrative hearing, and serving as an impartial decisionmaker,
    all with the goal of fairly and expeditiously adjudicating claims. For
    claims filed before March 27, 2017, the ALJ’s decision must account
    for the “treating physician rule”: If the record contains a treating
    physician’s opinion about the nature and severity of the claimant’s
    impairments, the ALJ must determine whether, in light of the
    3
    administrative record, that opinion is entitled to controlling weight,
    or something less. Congress has authorized federal courts to engage
    in limited review of final agency decisions in Social Security disability
    cases. We may vacate the agency’s disability determination only if it
    is based on legal error or unsupported by “substantial evidence”—
    that is, if no reasonable factfinder could have reached the same
    conclusion as the ALJ.
    In May 2016, Plaintiff-Appellant Brenda Lynn Schillo filed a
    claim for Social Security Disability Insurance and Supplemental
    Security Income benefits. Schillo claimed disability based on her
    medical conditions of cerebral palsy, fibromyalgia, benign tremors,
    and osteoarthritis. Schillo relied, in part, on opinions of two of her
    treating physicians. After a hearing, an ALJ assigned only partial
    weight to the treating physicians’ opinions. Based on all of the
    medical evidence in the record, the ALJ determined that Schillo was
    not disabled because her residual functional capacity (“RFC”) still
    4
    allowed her to perform her past relevant work as a project manager.
    Schillo challenged this determination through the agency
    appeals process and then in the United States District Court for the
    Northern District of New York (Thérèse Wiley Dancks, M.J.), but both
    times the ALJ’s decision was upheld. She now appeals the denial of
    benefits, arguing primarily that (1) the ALJ’s RFC determination (and
    particularly the ALJ’s assignment of lesser weight to the treating
    physicians’ opinions) was not supported by substantial evidence; and
    (2) the ALJ committed procedural error by failing to explicitly
    consider certain factors listed in 
    20 C.F.R. § 404.1527
    (c) when deciding
    how much weight to accord the treating physicians’ opinions.
    We find Schillo’s arguments unpersuasive and therefore affirm.
    In doing so, we recognize that adjudication of Social Security
    disability claims is a highly case-specific endeavor that depends on
    the objective medical evidence in the administrative record. Upon
    review of this record, we hold that substantial evidence supported the
    5
    ALJ’s determinations and that any procedural error was harmless.
    I.   Background
    A. Statutory & regulatory framework
    Subchapter II of the Social Security Act, 
    42 U.S.C. §§ 401
    –434,
    sets forth the benefits available to an eligible claimant who is
    “disabled.” Under 
    42 U.S.C. § 423
    (d)(1)(A), “[a] claimant is disabled
    and entitled to disability insurance benefits if she is unable . . . ‘to
    engage in any substantial gainful activity by reason of any medically
    determinable physical or mental impairment which can be expected
    to result in death or which has lasted or can be expected to last for a
    continuous period of not less than 12 months.’” Cichocki v. Astrue, 
    729 F.3d 172
    , 176 (2d Cir. 2013) (quoting 
    42 U.S.C. § 423
    (d)(1)(A)). The
    “ultimate finding of whether a claimant is disabled and cannot work
    [is] ‘reserved to the Commissioner.’” Snell v. Apfel, 
    177 F.3d 128
    , 133
    (2d Cir. 1999) (quoting 
    20 C.F.R. § 404.1527
    (e)(1) (1991)). To make that
    finding, the agency follows a five-step process detailed in 20 C.F.R.
    6
    § 404.1520(a)(4)(i)–(v).   “If at any step a finding of disability or
    nondisability can be made, the [Commissioner] will not review the
    claim further.” Barnhart v. Thomas, 
    540 U.S. 20
    , 24 (2003); see also 
    20 C.F.R. § 404.1520
    (a)(4).
    Under the five-step process, the Commissioner determines:
    (1) whether the claimant is currently engaged in substantial gainful
    activity; (2) whether the claimant has a severe physical or mental
    impairment, or combination of severe impairments; (3) whether the
    impairment (or combination) meets or equals the severity of one of
    the impairments specified in 20 C.F.R. Part 404, Subpart P, Appendix
    1 (“Listing of Impairments”); (4) whether, based on an assessment of
    the claimant’s residual functional capacity, the claimant can perform
    any of her past relevant work; and (5) whether the claimant can make
    an adjustment to other work given the claimant’s residual functional
    capacity, age, education, and work experience.              
    20 C.F.R. § 404.1520
    (a)(4)(i)–(v). “The claimant bears the burden of proof in the
    7
    first four steps of the sequential inquiry.” Selian v. Astrue, 
    708 F.3d 409
    , 418 (2d Cir. 2013). In step five, the burden shifts, to a limited
    extent, to the Commissioner to show that other work exists in
    significant numbers in the national economy that the claimant can do.
    
    20 C.F.R. § 404.1560
    (c)(2); see Poupore v. Astrue, 
    566 F.3d 303
    , 306 (2d
    Cir. 2009). Because the shift in step five is limited, the Commissioner
    “need not provide additional evidence of the claimant’s residual
    functional capacity.”     Poupore, 556 F.3d at 306; see 
    20 C.F.R. § 404.1560
    (c)(2).
    The ultimate finding of whether the claimant is disabled is
    reserved to the agency; but where the record includes the opinions of
    treating physicians, “the Social Security Administration considers the
    data that [their opinions] provide [and then] draws its own
    conclusions as to whether those data indicate disability.” Snell, 
    177 F.3d at 133
    .   A treating physician’s opinion that the claimant is
    disabled may carry particular weight, but it is not itself determinative
    8
    of that finding. 
    Id.
    For claims filed before March 27, 2017 (as is the case here), the
    agency must apply 
    20 C.F.R. § 404.1527
    . Pursuant to that regulation,
    the ultimate finding on the claimant’s residual functional capacity is
    reserved to the Commissioner. 20 C.F.R § 404.1527(d)(2). In making
    that finding, the agency “use[s] medical sources, including [the
    claimant’s] treating source, to provide evidence, including opinions,
    on the nature and severity of [the claimant’s] impairment(s).” Id. The
    agency must follow what is commonly called the “treating physician
    rule” when considering the opinion of a claimant’s treating source: If
    the agency finds “that a treating source’s medical opinion on the
    issue(s) of the nature and severity of [the claimant’s] impairments is
    well-supported by medically acceptable clinical and laboratory
    diagnostic techniques and is not inconsistent with the other
    substantial evidence in [the] case record, [the agency] will give it
    controlling weight.” Id. The agency has adopted new regulations for
    9
    claims filed on or after March 27, 2017, which change how the agency
    considers the opinions of treating sources. 1                 Accordingly, our
    application of the treating physician rule in this opinion is limited to
    claims like Schillo’s that were filed before the effective date of the new
    regulation and are therefore still governed by 
    20 C.F.R. § 404.1527
    .
    B. Administrative proceedings
    Schillo’s background is laid out in detail in the administrative
    record. As relevant here, she received a high school diploma, later
    attended vocational school for computer systems operations, and in
    1 On January 18, 2017, the Social Security Administration promulgated the
    regulations now found at 
    20 C.F.R. §§ 404
    .1520c and 416.920c, which apply to
    claims filed on or after March 27, 2017. Revisions to Rules Regarding the
    Evaluation of Medical Evidence, 
    82 Fed. Reg. 5844
    , 5853 (Jan. 18, 2017). For these
    cases, the new regulations no longer apply the treating physician rule. See 
    id.
    (“[W]e are not retaining the treating source rule in final 404.1520c and 416.920c for
    claims filed on or after March 27, 2017.”). Going forward, the agency “will not
    defer or give any specific evidentiary weight, including controlling weight, to any
    medical opinion(s) or prior administrative medical finding(s), including those
    from [a claimant’s] medical sources.” 
    20 C.F.R. § 404
    .1520c(a). The agency will
    instead consider the factors found at § 404.1520c(c) during its review of these
    sources.
    It is undisputed that Schillo filed her claim on May 19, 2016, and that the
    earlier regulation therefore applies to this case.
    10
    2005 obtained a real estate license (which has since expired). Schillo
    has worked as a service repair coordinator (the last position she held),
    an office assistant, a self-service administrator, a customer service
    representative, a data analyst, an accounts payable clerk, and a project
    specialist. Schillo has not worked since May 17, 2016. She states that
    she stopped working due to chronic pain and fatigue from
    fibromyalgia.     Through her employer, she was on short-term
    disability until November 2016 but was denied long-term disability
    benefits.
    On    May    19,   2016,   Schillo   filed   a   claim   for   Social
    Security Disability Insurance and Supplemental Security Income
    benefits based on cerebral palsy, fibromyalgia, benign tremors, and
    osteoarthritis, alleging a disability onset date of May 17, 2016. The
    SSA denied Schillo’s application on August 1, 2016. Schillo then
    requested a hearing before an ALJ.
    The ALJ held a video hearing on April 11, 2018, at which Schillo
    11
    was represented by counsel. During the hearing, the ALJ questioned
    Schillo about her family and living situation, financial assistance,
    employment history, daily activities, medical conditions, and
    symptoms she experienced from those conditions.            The ALJ
    considered the administrative record, which includes MRI results, x-
    ray results, and notes documenting Schillo’s visits with different
    health care providers, including Arthritis Health Associates and the
    Bone and Joint Center. The record also contains notes from Schillo’s
    visits with her treating physicians—Dr. Hassan Shukri, her
    neurologist, and Dr. Michael Picciano, her primary care provider.
    Further, the record contains the opinion of consultative examiner Dr.
    Kalyani Ganesh, from whom the SSA’s Division of Disability
    Determination had requested an internal medicine examination in
    connection with Schillo’s claim for disability.
    The ALJ issued her findings of fact and conclusions of law on
    May 25, 2018. The ALJ concluded that Schillo had not been under a
    12
    disability within the meaning of the Social Security Act from May 17,
    2016, through the date of the ALJ’s decision. She therefore denied
    Schillo’s claim for disability. In reaching this conclusion, the ALJ
    made the following findings: First, Schillo met the insured status
    requirements of the Social Security Act through December 31, 2021.
    Second, Schillo had not engaged in substantial gainful activity since
    May 17, 2016. Third, Schillo had the following severe impairments:
    fibromyalgia, Charcot-Marie-Tooth disease, essential tremor, and
    osteoarthritis.   Fourth, Schillo did not have an impairment or
    combination of impairments that meets or medically equals the
    severity of one of the listed impairments in the Listing of
    Impairments. Fifth, Schillo had the residual functional capacity to lift,
    carry, push, or pull twenty pounds occasionally and ten pounds
    frequently, sit for six hours, and stand and/or walk for six hours in an
    eight-hour day. She could frequently balance and stoop; occasionally
    kneel, crouch, climb ramps, climb stairs, and operate foot controls;
    13
    and never crawl or climb ladders, ropes, or scaffolds. Schillo could
    have no exposure to vibration or workplace hazards, including
    unprotected heights and moving mechanical parts.          She could
    frequently handle, finger, and feel with her dominant right hand, and
    she could occasionally handle, finger, and feel with her non-dominant
    left hand. Lastly, Schillo was capable of performing past relevant
    work as a project manager, because it did not require the performance
    of work-related activities precluded by Schillo’s RFC.
    In assessing Schillo’s RFC, the ALJ weighed the opinions of her
    treating physicians and determined that they should not be afforded
    controlling weight. First, the ALJ addressed the conclusory nature of
    Dr. Shukri’s opinions. On May 19, 2016, Dr. Shukri opined that most
    of Schillo’s symptoms will “get worse with age” making it “very
    difficult for her to do any physical job”; Dr. Shukri thus noted that
    Schillo could “[m]aybe . . . qualify for social security disability.”
    Admin. R. on Appeal at 285. On October 5, 2016, Dr. Shukri opined
    14
    that Schillo “is unable to perform any job because of [her] tremor.” Id.
    at 486. And on more than one occasion Dr. Shukri concluded that
    Schillo is “permanently totally disabled.” Id. at 356; see also id. at 487
    (“For now we will consider her permanently totally disabled because
    of the tremor and the spasticity in bilateral lower extremities.”). The
    ALJ found that those opinions were “conclusory” and “did not speak
    to [Schillo’s] specific physical capabilities or limitations.” App’x at 75.
    The ALJ also found the terms Dr. Shukri used—such as “physical
    job,” “very difficult,” and “might qualify”—to be “vague, undefined
    terms with regard to the determination of an individual’s residual
    functional capacity and therefore open to interpretation, giving them
    little utility in making such a determination.” Id. Accordingly, the
    ALJ afforded little weight to these opinions.
    Second, the ALJ found inconsistencies between Dr. Shukri’s
    opinions and the objective medical evidence, which included his own
    treatment notes. The ALJ highlighted that Dr. Shukri had concluded
    15
    that Schillo’s bilateral hand tremors “would make fine manipulation
    impossible,” but “[t]he medical record shows [Schillo] generally has
    mild right-sided tremors and mild to moderate left-sided tremors,
    which does not suggest a total inability to engage in fine manipulation
    with either hand.” App’x at 75–76. The ALJ further pointed to
    Schillo’s own testimony establishing her ability to engage “in several
    activities that require fine manipulation, including driving a vehicle,
    dressing, bathing, preparing meals, doing chores, and using a
    cellphone.” Id. at 76. In sum, because the ALJ found Dr. Shukri’s
    opinions to be an “overstatement” of Schillo’s manipulative
    limitations, the ALJ afforded his opinions partial weight and assigned
    limitations on Schillo’s RFC that “are more commensurate with the
    objective evidence.” Id.
    The ALJ also gave partial weight to the opinions of Dr. Picciano.
    Most of Dr. Picciano’s opinions of Schillo’s RFC were submitted in
    February 2018 on a check-marked worksheet endorsing specific
    16
    limitations with almost no explanation. According to this worksheet,
    Schillo (1) experiences for over 30% of the workday symptoms severe
    enough to interfere with the attention and concentration needed to
    perform simple work tasks; (2) cannot walk more than one city block
    without experiencing pain or needing to rest; (3) can sit for only ten
    minutes before needing to get up; (4) can stand for no more than
    twenty minutes before needing to sit down; (5) cannot “sit and
    stand/walk” for more than two hours in an eight-hour workday (with
    normal breaks); (6) needs a job that permits shifting positions at will
    from sitting, standing, or walking; (7) needs ten-minute breaks each
    hour of an eight-hour workday; (8) can lift items weighing less than
    ten pounds only occasionally; (9) can use her right hand for gross
    manipulation for 20% of the workday and for fine manipulation for
    10% of the workday, but can never use her left hand for gross or fine
    manipulation; and (10) on average will likely be absent from work for
    more than four days per month as a result of her impairments.
    17
    Admin. R. on Appeal at 407–09. That same month, Dr. Picciano
    opined that Schillo “is unable to work and has been unable to work
    since 5/2016 due to the effects of multiple neurological and
    musculoskeletal disorders.” Id. at 410. The ALJ afforded some weight
    to Dr. Picciano’s opinions because they “support[ed] some measure
    of exertional, postural, and manipulative limitations, which [were]
    consistent with the longitudinal record.” App’x at 76. But, like Dr.
    Shukri’s opinion, the ALJ found that the manipulative limitations
    suggested by Dr. Picciano did “not match up with the evidence
    showing mild tremor symptoms and sensory deficits in the right
    dominant hand and mild to moderate symptoms in the left.” Id.
    Accordingly, because the ALJ found that Dr. Picciano’s opinions
    deviated from the objective medical evidence, they were entitled to
    no more than partial weight. Id.
    Finally, the ALJ gave little weight to the opinion of the
    consultative examiner, Dr. Ganesh, that Schillo’s overall movements
    18
    were very brisk and that she had no physical difficulties.          Dr.
    Ganesh’s examination of Schillo had resulted in few abnormal
    findings. The ALJ concluded that this was inconsistent with the
    longitudinal evidence, which instead indicated “ongoing problems
    with hand tremors, neuropathic symptoms, and fibromyalgia, all of
    which contribute to functional limitations.” Id. at 76–77. Although
    the ALJ found that the opinions of Schillo’s treating physicians
    overstated Schillo’s limitations in light of the objective evidence, the
    ALJ gave them more weight than the opinion of Dr. Ganesh because
    they were “more consistent with a preponderance of the evidence
    than [Dr. Ganesh’s finding of] no limitations at all.” Id.
    C. Review of the ALJ’s decision
    Schillo sought review of the ALJ’s May 25, 2018, decision by the
    SSA’s Appeals Council. The Appeals Council denied her request on
    January 15, 2019, making the ALJ’s decision the final decision of the
    Commissioner. On August 12, 2019, Schillo filed a complaint in the
    19
    United States District Court for the Northern District of New York
    seeking judicial review of the Commissioner’s decision. The district
    court issued a memorandum decision and order affirming the
    Commissioner’s denial of Schillo’s application for Social Security
    benefits on September 29, 2020, and entered judgment that same day.2
    On November 20, 2020, Schillo filed this timely appeal.
    II.      Standard of review
    Congress has authorized federal courts to engage in limited
    review of final SSA disability benefit decisions. “On an appeal from
    the denial of disability benefits, we focus on the administrative ruling
    rather than the district court’s opinion.” Estrella v. Berryhill, 
    925 F.3d 90
    , 95 (2d Cir. 2019) (internal quotation marks omitted). That is
    because the same standard of review applies to the agency’s decision,
    both in the district court and before a court of appeals: “The findings
    of the Commissioner of Social Security as to any fact, if supported by
    2   On September 6, 2019, Schillo consented to the jurisdiction of a magistrate
    judge.
    20
    substantial evidence, shall be conclusive . . . .” 
    42 U.S.C. § 405
    (g).
    “We conduct a plenary review of the administrative record to
    determine if there is substantial evidence, considering the record as a
    whole, to support the Commissioner’s decision and if the correct legal
    standards have been applied.”       Estrella, 925 F.3d at 95 (internal
    quotation marks omitted). The “substantial evidence” standard is “a
    very deferential standard of review—even more so than the ‘clearly
    erroneous’ standard.” Brault v. Soc. Sec. Admin., Comm'r, 
    683 F.3d 443
    ,
    448 (2d Cir. 2012). “Indeed, it is not our function to determine de novo
    whether a plaintiff is disabled.” 
    Id. at 447
     (alterations and internal
    quotation marks omitted). “Substantial evidence” is “such relevant
    evidence as a reasonable mind might accept as adequate to support a
    conclusion.” Richardson v. Perales, 
    402 U.S. 389
    , 401 (1971) (internal
    quotation marks omitted); see also Brault, 683 F.3d at 448.         “In
    determining whether the agency’s findings were supported by
    substantial evidence, the reviewing court is required to examine the
    21
    entire record, including contradictory evidence and evidence from
    which conflicting inferences can be drawn.” Selian, 708 F.3d at 417
    (internal quotation marks omitted). “If evidence is susceptible to
    more than one rational interpretation, the Commissioner’s conclusion
    must be upheld.” McIntyre v. Colvin, 
    758 F.3d 146
    , 149 (2d Cir. 2014).
    “The substantial evidence standard means once an ALJ finds facts, we
    can reject those facts ‘only if a reasonable factfinder would have to
    conclude otherwise.’” Brault, 683 F.3d at 448 (emphasis added in Brault)
    (quoting Warren v. Shalala, 
    29 F.3d 1287
    , 1290 (8th Cir. 1994)). We
    “require that the crucial factors in any determination be set forth with
    sufficient specificity to enable us to decide whether the determination
    is supported by substantial evidence.”        Estrella, 925 F.3d at 95
    (alterations and internal quotation marks omitted).
    III.   Discussion
    Schillo advances two related arguments, both of which turn on
    the treating physician rule. She contends first that the ALJ’s RFC
    22
    determination was not supported by substantial evidence because
    what the ALJ articulated as “good reasons” for discounting the
    treating physicians’ opinions were not, in fact, backed up by the
    record. Schillo’s second argument is essentially procedural: that in
    spelling out “good reasons” for according less than controlling weight
    to the treating physicians’ opinions, the ALJ failed to expressly walk
    through certain mandatory factors outlined in 
    20 C.F.R. § 404.1527
    .
    As our precedents have held, when applying 
    20 C.F.R. § 404.1527
    , there are “specific procedures that an ALJ must follow in
    determining the appropriate weight to assign a treating physician’s
    opinion. First, the ALJ must decide whether the opinion is entitled to
    controlling weight.”   Estrella, 925 F.3d at 95.   The opinion of a
    claimant’s treating physician as to the nature and severity of the
    impairment is given controlling weight so long as it is well supported
    by medically acceptable clinical and laboratory diagnostic techniques
    and is not inconsistent with (or contradicted by) other substantial
    23
    evidence in the claimant’s case record. See Burgess v. Astrue, 
    537 F.3d 117
    , 128 (2d Cir. 2008); 
    20 C.F.R. § 404.1527
    (c)(2). “[T]he ALJ cannot
    arbitrarily substitute his own judgment for competent medical
    opinion,” Rosa v. Callahan, 
    168 F.3d 72
    , 79 (2d Cir. 1999) (internal
    quotation marks omitted); rather, the ALJ’s assessment of the relevant
    opinion must always be supported by substantial evidence in the
    record. “Second, if the ALJ decides the opinion is not entitled to
    controlling weight, it must determine how much weight, if any, to
    give it.” Estrella, 925 F.3d at 95. The governing regulations require an
    ALJ to explicitly consider certain nonexclusive factors when making
    this determination: “(1) the frequency, length, nature, and extent of
    treatment; (2) the amount of medical evidence supporting the
    opinion; (3) the consistency of the opinion with the remaining medical
    evidence; and (4) whether the physician is a specialist.” Id. at 95–96
    (alterations and internal quotation marks omitted) (summarizing 
    20 C.F.R. § 404.1527
    (c)).   Even though this list of considerations is
    24
    established by regulation, we discussed them at length in Burgess v.
    Astrue, 
    537 F.3d at 129
    , and so they are sometimes referred to as the
    “Burgess factors.”
    At both steps, the regulations require the ALJ to give “good
    reasons”—i.e., reasons supported by substantial evidence in the
    record—for the weight she affords the treating source’s medical
    opinion. See Estrella, 925 F.3d at 96; see also 
    20 C.F.R. § 404.1527
    (c)(2).
    Indeed, our Court did not hesitate to remand in our recent decision in
    Colgan v. Kijakazi, where the ALJ failed to provide good reasons at step
    one for discounting a treating physician’s opinion. 
    22 F.4th 353
    , 360
    (2d Cir. 2022). The ALJ there erroneously relied on a “one-time
    snapshot” of the claimant’s mental health status to find that the
    physician’s opinion was inconsistent with the objective medical
    evidence. 
    Id. at 362
    .
    If the ALJ proceeds to step two, she must explicitly apply the
    factors listed in § 404.1527; the failure to do so is procedural error and
    25
    subject to harmless error analysis. Estrella, 925 F.3d at 95–96; Colgan,
    F.4th at 359 n.3. A court can conclude that such an error is harmless
    if the ALJ has otherwise provided “good reasons” for its weight
    assignment. See Estrella, 925 F.3d at 96. For instance, our Court has
    upheld an ALJ’s denial of disability benefits even where the ALJ’s
    written opinion failed to assist our review on appeal and did not
    “generate much confidence in the result.” Halloran v. Barnhart, 
    362 F.3d 28
    , 31–33 (2d Cir. 2004). In Halloran, it was “unclear on the face
    of the ALJ’s opinion whether the ALJ considered (or even was aware
    of) the applicability of the treating physician rule,” but the Court
    concluded, “[a]fter carefully considering the entire record and the
    ALJ’s opinion,” that the ALJ had applied the substance of the rule. 
    Id. at 32
    .   The ALJ explained that the treating physician’s two key
    findings were conclusory given that he provided them on an
    “uninformative response to a multiple-choice question about [the
    claimant’s] ability to sit,” and that he “did not address the question of
    26
    whether [the claimant] could do the job if given several breaks or
    allowed to change position often.” 
    Id.
     (internal quotation marks
    omitted). The ALJ’s explanation thereby struck the Court as an
    application of the substance of the treating physician rule. See also
    Estrella, 925 F.3d at 96 (where “‘a searching review of the record’
    assures us ‘that the substance of the treating physician rule was not
    traversed,’ we will affirm” (quoting Halloran, 
    362 F.3d at 32
    )).
    A. The ALJ’s RFC assessment was supported by
    substantial evidence
    We turn first to Schillo’s claim that the ALJ’s assessment of the
    treating physicians’ opinions, and ultimately of her RFC, was
    unsupported by substantial evidence. Here, at step one, the ALJ did
    not afford controlling weight to the opinions of Schillo’s treating
    physicians. 3 We hold that the reasons the ALJ provided—that their
    3 Although the ALJ here did not expressly state that she would not afford
    “controlling” weight to the opinions of Schillo’s treating physicians, that much is
    clear given that the ALJ ultimately concluded that Dr. Shukri’s opinions would
    receive little and partial weight and that Dr. Picciano’s opinions would receive
    partial weight.
    27
    opinions were conclusory, unhelpful with respect to assessing RFC,
    and inconsistent with the objective medical evidence—were “good
    reasons” supported by substantial evidence.
    The ALJ reasonably determined that Dr. Shukri’s conclusory
    opinion that Schillo was disabled was not entitled to controlling
    weight.     Dr. Shukri’s statement—standing alone—cannot be
    determinative of Schillo’s disability status. See Snell, 
    177 F.3d at 133
    .
    And what accompanies Dr. Shukri’s opinion are conclusory words as
    to how Schillo will “[m]aybe qualify” for disability benefits and that
    it might be “very difficult” for her to do any “physical job.” Admin.
    R. on Appeal at 285. The ALJ was entitled to conclude that these
    statements were too vague to be of much help in a concrete
    assessment of Schillo’s RFC, and that Dr. Shukri’s opinion was
    therefore entitled to only limited weight.
    Schillo contends that “the ALJ was duty bound to obtain a more
    detailed and clarified statement from Dr. Shukri before rejecting
    28
    statements due to ‘vague, undefined terms.’” Appellant’s Br. at 49.
    We disagree. To be sure, a hearing on disability benefits is a non-
    adversarial proceeding. An ALJ generally has an affirmative duty to
    develop the administrative record, including when there are
    deficiencies in the record. Burgess, 
    168 F.3d at 79
    ; Rosa, 
    168 F.3d at 79
    .
    But a deficiency in reasoning by a treating physician is not the same
    as a gap in treatment records. In other circumstances, we have
    concluded that an ALJ should have sought additional information to
    fill a record consisting only of sparse and conclusory notes of a single
    treating physician. Rosa, 
    168 F.3d at
    79–80; see also Pratts v. Chater, 
    94 F.3d 34
    , 38 (2d Cir. 1996) (concluding that the record offered “no basis
    to find the substantial evidence necessary to uphold the ALJ’s
    decision” given that much of the claimant’s medical history was
    missing and that the medical records appearing in the record were
    frequently incomplete or illegible, providing “no coherent overview
    of [the claimant’s] treatment”).      Here, by contrast, there was a
    29
    complete record before the ALJ consisting of medical opinions,
    treatment notes, and test results from 2016 to 2018, as well as Schillo’s
    own testimony. The ALJ pointed to specific portions of the record
    that undercut Dr. Shukri’s opinion that Schillo had a total inability to
    manipulate both hands.       Schillo has not identified any missing
    medical records that should have been included in the record, and we
    are aware of none. Accordingly, the ALJ did not err in failing to
    supplement the administrative record.
    Similarly, the ALJ provided good reasons for not affording
    controlling weight to Dr. Picciano’s check-box form medical opinion.
    As we recently made clear, there is no rule that “the evidentiary
    weight of a treating physician’s medical opinion can be discounted by
    an ALJ based on the naked fact that it was provided in a check-box
    form.” Colgan, 22 F.4th at 361. An ALJ may, however, discount a
    treating physician’s opinion—regardless of its form—if it is not
    supported by substantial evidence in the record. For example, in
    30
    Halloran, the treating physician’s medical report was “prepared on a
    standardized, multiple-choice ‘New York State Office of Temporary
    and Disability Assistance’ Form, which elicits information about the
    patient’s ability to do work-related physical activities.” Halloran, 
    362 F.3d at 31
    .   “Among other designations,” the treating physician
    checked a box stating that the claimant “could sit for ‘less than 6 hours
    per day.’” 
    Id.
     Because the treating physician’s opinions “were not
    particularly informative and were not consistent with those of several
    other medical experts,” we concluded that they were not entitled to
    controlling weight.    
    Id. at 32
    . Conversely, we recently vacated an
    ALJ’s decision not to afford controlling weight to a treating
    physician’s check-box form opinion. Colgan, 22 F.4th at 362. As we
    explained in Colgan: “In contrast to the medical report at issue in
    Halloran—which completely lacked any supporting evidence in the
    medical record—[the treating physician’s] check-box form opinion
    [here] was supported by voluminous treatment notes gathered over
    31
    the course of nearly three years of clinical treatment.” Id. (emphasis
    added).
    On balance, Dr. Picciano’s opinion is more akin to that of the
    treating physician in Halloran: it deviates from the consistent 2016 to
    2018 medical evidence showing only mild tremor symptoms and
    sensory deficits in Schillo’s right dominant hand and mild to
    moderate symptoms in Schillo’s left hand. 4 The ALJ found notable
    inconsistencies       between       Dr.    Picciano’s     conclusions        and    the
    longitudinal records of Schillo’s physical health—parsing through
    4 Further, Schillo’s testimony about her daily activities—including her
    ability to do chores around her house, bathe, dress, and use her cellphone—lends
    some support to the ALJ’s findings that both Drs. Shukri’s and Picciano’s opinions
    are inconsistent with the objective medical evidence. Of course, “[w]hen a
    disabled person gamely chooses to endure pain in order to pursue important
    goals, . . . it would be a shame to hold [that] endurance against him in determining
    benefits unless his conduct truly showed that he is capable of working.” Colgan, 22 F.4th
    at 363 (emphasis added) (internal quotation marks omitted). Schillo did not testify
    that she persevered through tremors or pain when completing all activities. For
    instance, she reported no difficulty with fine or gross hand or finger manipulation
    when doing her laundry, cleaning her home, or doing the dishes. Regardless of
    whether this testimony standing alone could have been sufficient to accord lesser
    weight to the treating physicians’ opinions, it bolsters what the ALJ found after a
    thorough review of the record: that during the relevant period, Schillo did not
    have a total inability to use her hands such that it would have precluded her from
    performing her past relevant work.
    32
    each data point and thus not resting the disability determination on
    an unrepresentative “one-time snapshot” of Schillo’s status. See, e.g.,
    Colgan, 22 F.4th at 362; Estrella, 925 F.3d at 97–98. In short, substantial
    evidence supported the ALJ’s decision to afford only limited weight
    to the opinion of Dr. Picciano. 5 We therefore cannot second-guess
    that decision on appeal. See Brault, 683 F.3d at 448.
    Having concluded that the ALJ’s assignment of lesser weight to
    Drs. Shukri’s and Picciano’s medical opinions was permissible, we
    also hold that substantial evidence supports the ALJ’s ultimate RFC
    determination. As the ALJ accorded the treating physicians’ opinions
    5   We note that the ALJ gave even less weight to the opinion of the
    consultative examiner, compared to the opinions of Drs. Shukri and Picciano. See
    App’x at 77 (“I gave more weight to the opinions of the claimant’s treating
    physicians who, although they overstated the claimant’s limitations in light of the
    objective evidence, were more consistent with a preponderance of the evidence
    than no limitations at all.”). “[W]e have frequently cautioned that ALJs should not
    rely heavily on the findings of consultative physicians after a single examination,”
    and so it can be problematic when an ALJ affords them more weight than a treating
    physician’s findings. Colgan, 22 F.4th at 363 (internal quotation marks omitted);
    see also Cruz v. Sullivan, 
    912 F.2d 8
    , 13 (2d Cir. 1990). That is not an issue here,
    where the ALJ engaged in a careful comparative assessment of the various medical
    opinions in the record and accorded relatively more (though ultimately non-
    determinative) weight to the opinions of the treating physicians.
    33
    lesser and not no weight, she still considered their conclusions to
    assess Schillo’s RFC. The ALJ also looked to the other sources in the
    administrative record, including MRI results, x-ray results, and notes
    documenting Schillo’s visits with other medical providers. Using
    these opinions and data points, the ALJ laid out with specificity
    Schillo’s physical capabilities. See supra pps. 13–14; see also Estrella,
    925 F.3d at 95. Under our very deferential standard of review, see
    Brault, 683 F.3d at 448, we cannot say that no reasonable factfinder
    could have reached the same conclusion—that an assessment of
    Schillo’s RFC showed that she could perform her past relevant work
    as a project manager.
    In reaching this conclusion, we also reject Schillo’s argument
    that, having declined to afford controlling weight to any of the three
    physicians’ opinions, the ALJ was thereby prohibited from making an
    RFC finding whatsoever.       The ALJ is permitted to discount the
    opinion of a treating physician if it is inconsistent with other
    34
    substantial evidence. See Halloran, 
    362 F.3d at 32
    . And the ALJ bears
    “the final responsibility” for making RFC determinations. 
    20 C.F.R. § 404.1527
    (d)(2). It follows from these basic principles that the ALJ’s
    RFC conclusion need not perfectly match any single medical opinion
    in the record, so long as it is supported by substantial evidence. See
    Richardson, 
    402 U.S. at 399
     (“We therefore are presented with the not
    uncommon situation of conflicting medical evidence. The trier of fact
    has the duty to resolve that conflict.”). In so holding, we here reiterate
    a point that this Court has previously made summarily. See Matta v.
    Astrue, 508 F. App’x 53, 56 (2d Cir. 2013) (stating that an ALJ’s
    conclusions need not “perfectly correspond with any of the opinions
    of medical sources cited in his decision” because the ALJ is “entitled
    to weigh all of the evidence available to make an RFC finding that [is]
    consistent with the record as a whole”).
    B. The ALJ’s procedural error was harmless
    Next, we consider Schillo’s claim that the ALJ committed an
    35
    error of law by failing to follow the correct procedures when applying
    the treating physician rule. Once the ALJ decided not to afford
    controlling weight to the treating physicians’ opinions, she was
    required to explicitly review the factors listed in 
    20 C.F.R. § 404.1527
    (c) to determine what (if any) lesser weight to give those
    opinions. See Burgess, 
    537 F.3d at 129
    . As the agency concedes, the
    ALJ failed to consider each factor explicitly and thereby committed a
    procedural error.
    But this is not the end of the road. Our examination of the
    record discloses that the ALJ nevertheless applied the substance of the
    treating physician rule.    The ALJ’s written decision effectively
    covered the factors listed in 
    20 C.F.R. § 404.1527
    (c)(2), including the
    nature of the examining and treating relationships, the supportability
    of the opinions, their consistency with the record as a whole, and the
    doctors’ specialization. With respect to Dr. Shukri’s background and
    proffered medical opinions, the ALJ explained that Dr. Shukri treated
    36
    Schillo from May 2016 into 2017; that Dr. Shukri’s opinion that
    Schillo’s bilateral hand tremors would make fine manipulation
    impossible was inconsistent with the objective findings and Schillo’s
    reported activities; and that Dr. Shukri, as a neurologist, is a specialist.
    As to Dr. Picciano, the ALJ similarly explained that Dr. Picciano
    treated Schillo between 2016 and 2018; that Dr. Picciano’s opinion
    with respect to Schillo’s hand and finger manipulation deviated
    significantly from the objective evidence; and that Dr. Picciano is not
    a specialist. 6   Furthermore, in assessing Schillo’s RFC, the ALJ
    articulated that although the body of medical evidence in the record
    supports the treating physicians’ opinions to the extent they
    concluded that Schillo had some physical limitations (which is why
    the ALJ still afforded some weight to their opinions), that evidence
    did not suggest that those limitations were so complete as to render
    6We glean this from the fact that the ALJ specified Dr. Shukri’s specialty—
    neurology—and omitted a specialty in her discussion of Dr. Picciano’s opinions.
    Further, the record makes clear that Dr. Picciano is Schillo’s primary care
    physician, not a specialist. See, e.g., Admin. R. on Appeal at 301, 424.
    37
    her disabled. For instance, the ALJ detailed how “[d]uring a detailed
    neurological examination, the claimant demonstrated no resting
    tremors, but she had mild to moderate low-amplitude action hand
    tremors that were worse on the left, with minimal to mild impairment
    in drawing and writing.” App’x at 74; see, e.g., 
    id.
     (summarizing
    results from Schillo’s examinations in 2017, including that Schillo
    presented no tremors or involuntary movements and a normal gait
    despite limited range of cervical motion bilaterally and that she was
    doing notably well on her medication).
    Accordingly, although the ALJ should have proceeded more
    methodically through the factors enumerated in § 404.1527(c)(2), it is
    evident that she “applied the substance of the treating physician
    rule.” Halloran, 
    362 F.3d at 32
    . The ALJ articulated “good reasons”
    for assigning little weight and partial weight to Dr. Shukri’s opinions
    and partial weight to Dr. Picciano’s opinions: their opinions were
    conclusory, inconsistent with the objective medical evidence, and
    38
    unhelpful in assessing Schillo’s RFC. The procedural error was
    therefore harmless. See Estrella, 925 F.3d at 96.
    We have considered Schillo’s remaining arguments and
    conclude that they lack merit.
    IV.   Conclusion
    To summarize, we hold as follows:
    1. Substantial evidence in the record supports (a) the
    ALJ’s assignment of less than controlling weight to the opinions
    of Schillo’s treating physicians about the nature and severity of
    her impairments pursuant to 
    20 C.F.R. § 404.1527
    , and (b) the
    ALJ’s finding that Schillo retained the residual functional
    capacity to perform her previous work as a project manager.
    2. The ALJ committed procedural error by failing to
    explicitly apply each of the factors listed in 
    20 C.F.R. § 404.1527
    (c) when determining what weight to assign the
    opinions of Schillo’s treating physicians. But that error was
    39
    harmless because the record establishes that the ALJ
    nevertheless applied the substance of the treating physician
    rule.
    For the foregoing reasons, we AFFIRM the judgment of the
    district court affirming the Commissioner’s denial of Schillo’s
    application for Social Security Disability Insurance and Supplemental
    Security Income benefits.
