    PER CURIAM
    In this case involving a physical altercation between a customer and an
    employee of defendant Lowe's Home Centers, LLC, plaintiffs appeal orders that:
    granted summary judgment in favor of Lowe's; granted partial summary
    judgment on negligence claims in favor of the Lowe's employee, defendant
    Ahmed Hassan; precluded portions of testimony of plaintiffs' vocational and
    economic experts; and permitted testimony of Lowe's' biomechanical-
    engineering expert. Lowe's cross-appeals the court's denial of its motion to bar
    plaintiffs' retail-industry expert and decision to preclude police officers' lay
    opinions about how the altercation occurred. Because the motion judges erred
    in granting the summary-judgment motions and in precluding in part testimony
    from plaintiffs' vocational and economic experts, we reverse those orders .
    A-0222-20
    2
    Because the motion judges did not err in permitting the testimony of plaintiffs'
    retail-industry expert and Lowe's' biomechanical-engineering expert, in barring
    opinion testimony of responding police officers, and in denying related
    reconsideration motions, we affirm those orders.
    I.
    Lowe's hired Hassan as a flooring customer sales associate on May 4,
    2017. Hassan previously had been employed by Lowe's as a cashier in the
    summers of 2013 and 2015. He had no prior experience as a customer sales
    associate or in the flooring department.          A customer sales associate is
    responsible for "[p]rovid[ing] superior customer service by assisting customers
    in selection, demonstration, and purchase of product[s] . . . [and] provid[ing]
    quick responsive customer service." A customer sales associate's "essential
    knowledge"     and   "skills"   include    "[u]nderstand[ing]   and    respond[ing]
    appropriately to basic customer . . . inquiries" and being able "to
    operate/demonstrate/explain merchandise in the assigned area." A customer
    sales associate is required to wear a clean uniform and a name tag. 2
    2
    According to an assistant manager at the store where Hassan was employed,
    new employees in training have a "training tag" on them so a customer can see
    the tag "and understand that, if they're not a subject matter expert, be a little bit
    more patient with them, where they might reach out to another associate for
    A-0222-20
    3
    According to plaintiffs' retail-industry expert, at the time of the parties'
    altercation, Hassan had not yet completed all of his training, including a
    computerized training module entitled "Impacting the Customer." That training
    module contained twenty-eight separate videos explaining how to interact with
    customers to create a "positive customer experience" and included one skit with
    instructions on how to interact with an upset customer and multiple videos with
    instructions on how to react to a customer who approaches and says, "You
    people must not know what you're doing . . . ." Hassan also had not received
    training on Lowe's written Workplace Violence Procedure, which defined
    workplace violence as including "aggressive contact directed toward another
    individual" and stated "[a]ny employee who commits workplace violence will
    be subject to disciplinary action up to and including termination." For their first
    seven to fourteen days, new employees are paired with a mentor, who is an
    associate in the store with a working knowledge of different areas of the store.
    According to a Lowe's training video, a new employee will receive training time
    to shadow more experienced employees before working by themselves and must
    assistance." A picture taken from a video recorded by a responding police
    officer's body camera shows Hassan was wearing a name tag at hip level. A
    photograph of the name tag showed it did not indicate Hassan was in training.

    earn a red vest before working alone and before helping customers. 3 Even
    though he was a new employee who had not completed his training and had not
    yet earned the red vest, Hassan was the only person assigned to work in the
    flooring department at the time of the altercation.
    On May 13, 2017, nine days after Lowe's had hired Hassan as a customer
    sales associate, plaintiff Ivan Tymiv, who worked in the construction field,4
    went to Lowe's with a client to purchase supplies, including grout, for a home-
    remodeling project. According to plaintiff, he entered an aisle, which contained
    grout, and saw his client talking to Hassan. Plaintiff overheard Hassan give the
    client inaccurate information about grout. Plaintiff wanted unsanded grout and
    asked Hassan which grout was unsanded. Hassan told him he did not need
    unsanded grout for the type of tile he would be using. Plaintiff disagreed with
    Hassan's advice and told him if he did not know what he was talking about, he
    3
    According to plaintiffs' retail-industry expert, these procedures – being paired
    with a more experienced co-worker, having an experienced co-worker assigned
    to the department where the new employee is working, and not permitting a new
    employee to work alone in a department until after completing a training period
    – are consistent with accepted and standard practices in the retail industry.
    4
    Plaintiff testified he was self-employed with another partner in a business.
    That business was called Eagle Team NYC, LLC, which, according to plaintiffs'
    economic expert, was a partnership formed by plaintiff's wife Oksana Tymiv
    and someone else in March 2017.
    A-0222-20

    should not say anything but should "[j]ust learn [a] little more about it, and then
    tell [it] to the customers."    Hassan became angry, screamed and cursed at
    plaintiff and the client, and said he had a Ph.D. in history and did not have to
    learn about "this shit." Hassan turned around and walked away.
    While holding a bag of grout, plaintiff and the client followed Hassan to
    the next aisle and repeatedly asked for his name. Hassan turned around, walked
    towards plaintiff, asked plaintiff what he was going to do, and hit the bottom of
    the grout bag with his hand, knocking it out of plaintiff's hand and into the air
    and causing it to burst open. Hassan also punched plaintiff in the face with his
    hand and a broom he was carrying and then ran away. Plaintiff told another
    employee he had been struck by an employee and told her he wanted to speak to
    a manager and the police. The police came but accused plaintiff of assaulting
    Hassan, asking him why Hassan had grout on his head and back. Plaintiff left
    the store in an ambulance and went to a hospital. He asserts he is totally disabled
    as a result of the injuries he sustained in the altercation.
    Hassan has a different recollection of the altercation.       According to
    Hassan, he approached plaintiff and the client and asked if he could be of any
    A-0222-20
    6
    assistance.5   Plaintiff asked him about the difference between sanded and
    unsanded grout.    After Hassan stated his understanding of the difference,
    plaintiff told him he should learn more. Hassan explained to him he was still in
    training and his knowledge was "very limited." Plaintiff questioned how Hassan
    could be working on the floor if he did not know the difference between sanded
    and unsanded grout. Hassan described plaintiff as going "immediately from zero
    to 100 angry." Believing the situation was becoming confrontational, Hassan
    walked away. Plaintiff followed him, yelling at him and demanding his name;
    Hassan was in fear for his life. He felt something hit the back of his neck, head,
    and shoulder. Hassan glanced back, saw "white stuff" on his shoulder and saw
    plaintiff with a clenched fist about to punch him. Hassan attempted to use a
    "sweeper" to block the punch, hitting plaintiff in the face with it. Hassan
    described his actions as a "defensive measure." As plaintiff continued to follow
    him, Hassan found a co-worker, told her he had been assaulted, asked her to call
    5
    Contrary to the Lowe's training video stating a new employee in training must
    earn the red vest before helping customers, Lowe's' regional human resources
    manager for the store where Hassan was employed testified all customer service
    associates, even those still in training, are encouraged to approach customers "to
    give them service and to help them." The store manager also testified an
    employee in training could approach a customer before earning a red vest.

    security and the police, and went to a break room. After leaving the store that
    day, Hassan never returned and was fired for job abandonment.
    II.
    Plaintiff and his wife Oksana Tymiv filed a complaint against Lowe's and
    Hassan and subsequently amended the complaint. Plaintiffs alleged Lowe's
    negligently supervised and trained defendant Hassan.6 In a subsequent letter,
    plaintiffs' counsel advised defense counsel plaintiffs were amending their
    interrogatory answers to state "Hassan was acting within the scope of his
    employment at the time of the incident and therefore . . . Lowes is vicariously
    liable under the doctrine of respondeat superior."       In addition to asserting
    generally Hassan was negligent, plaintiffs alleged in the amended complaint
    Hassan's conduct constituted the "intentional and offensive tort of battery."
    During the course of discovery, Lowe's produced a report prepared by a
    purported biomechanical-engineering expert, Jacob L. Fisher, who opined the
    "grout bag was not launched into the air by a single blow from [Hassan], rather
    it was thrown . . . on a trajectory that roughly paralleled the path taken by
    6
    We take that summary of plaintiffs' allegations from plaintiffs' appellate brief.
    To the extent plaintiffs' amended complaint could be interpreted as containing
    other allegations concerning Lowe's, we do not address them because plaintiffs
    did not address them. See N.J. Dep't of Env't Prot. v. Alloway Twp., 
    438 N.J. Super. 501
    , 505 n.2 (App. Div. 2015).

    [Hassan] along the aisle." Given his findings regarding the trajectory of the
    grout bag, he concluded plaintiff's account of the altercation to be "inconsistent
    with the physical evidence gathered and recorded" while Hassan's account was
    "largely consistent" with the evidence.
    Plaintiffs produced a report from a "retail industry consultant," Alex J.
    Balian, who opined Lowe's had failed to follow its own employee-training
    procedure or the industry standard for training and had been negligent in its
    supervision of Hassan. Plaintiffs also produced a report from a vocational
    expert, Edmond Provder, who opined because of the injuries plaintiff had
    sustained in the altercation, plaintiff is unable to continue his work as a
    construction supervisor, in which he could earn annually $75,000. Provder
    estimated plaintiff had sustained a total loss of $2,340,000 in earning capacity.
    Plaintiffs also produced a report from economist Kristin Kucsma, who evaluated
    "the economic losses" to plaintiff as a result of his alleged injury and concluded
    the "total present value of past and future pecuniary losses" resulting from his
    alleged injury was $3,418,466.
    After discovery closed, the parties moved in limine to exclude each other's
    experts' testimony and plaintiffs moved to bar opinion and other testimony from
    the police officers who responded to the subject incident.
    A-0222-20
    9
    The motion judge denied Lowe's' motion to bar the testimony of plaintiffs'
    retail-industry expert, finding Balian to be qualified to render the opinion
    "because of his hands-on experience in training managers and employees in
    retail stores" and "vast exposure to training manuals and operating procedures
    of retail stores throughout the country." The judge also found Balian's opinion
    was based on "generally-accepted standards in the industry and is not a net
    opinion" and that "[t]he standard of care required for training and supervising
    employees in the retail industry is not something which the average juror would
    be able to determine." The motion judge subsequently denied Lowe's' motion
    for reconsideration of the denial of this motion.
    The motion judge denied plaintiffs' motion to bar the testimony of Lowe's'
    biomechanical expert, finding his expertise was "outside the ken of the average
    juror and [his opinion] is not a net opinion."
    The motion judge granted plaintiffs' motion to bar the testimony of the
    police officers, precluding them from testifying about "their opinions of how the
    incident occurred" but permitting them to testify about "any factual issues that
    they observed, including plaintiff's demeanor, [being] evasive with answers,
    defensive, arrogant, and the like." Denying Lowe's' subsequent motion for
    reconsideration of that decision, the motion judge again held the police officers
    A-0222-20
    10
    could testify about their personal observations, such as where the grout was
    located, but could not testify as to "their opinion about who with what."
    Lowe's moved for summary judgment, arguing plaintiffs could not
    establish Lowe's was negligent in hiring, training, or supervising Hassan
    because plaintiffs failed to establish Lowe's had breached any standard of care
    and Lowe's could not be held vicariously liable for Hassan's alleged battery
    because his actions were not within the scope of his employment.
    The motion judge granted Lowe's' summary-judgment motion, dismissing
    with prejudice plaintiffs' complaint against Lowe's. Viewing the case as "an
    assault," the judge held plaintiff had failed to prove "proximate cause between
    the lack of training of defendant Hassan, red vest status, lack of name tag, or
    shadowing polices and the assault of plaintiff by defendant Hassan." In addition,
    the motion judge found Lowe's could not be held vicariously liable because
    "there are no facts that a rational fact finder could construe that . . . Hassan . . .
    assaulted plaintiff [in] an effort to serve the employer, Lowe's." The motion
    judge also found Lowe's could not be held responsible because Hassan's actions
    were "clearly inappropriate or unforeseeable" and "totally unexpected ." The
    judge concluded Lowe's' "training or lack of is simply not applicable to this
    case."
    A-0222-20
    11
    Lowe's moved to bar the testimony of plaintiffs' vocational and economic
    experts. Hassan joined in that motion. A different motion judge granted in part
    and denied in part that motion. The motion judge held the experts could testify
    about "life plans" given the "underlying medical testimony." "[W]ith respect to
    the future economic loss," he held plaintiffs could not "use or rely on testimony
    [about] a $75,000 annual salary" calculation. The judge found both "experts
    have offered a net opinion about loss wages. There is no evidence in the record
    that this – salary has ever been [earned] – by the plaintiff." The judge held:
    The expert, as far as it can be determined, – selected an
    employment – through the Department of Labor
    statistics, opined that the plaintiff was qualified for that
    position and that the average salary that was listed on
    that table should be the foundation for which economic
    calculations should be based. There is not enough
    factual material . . . that would support that figure as
    being the equivalent of a lodestar for calculating
    economic loss.
    The motion judge also rejected plaintiffs' attempt to prorate plaintiff's income
    from certain months to calculate economic loss. The judge found:
    Again because of the nature . . . of his business, . . . to
    rely on the proposed number . . . projections of a newly
    formed, self-owned business are not truly factual. Such
    a business is subject to the uncertainties in changing
    economic conditions. The sample size is too small to
    extrapolate . . . $91,000 a year--; especially since no
    further evidence has been provided regarding costs and
    expenses of the ongoing business. . . . [I]t may not be
    A-0222-20
    12
    relied upon by the plaintiff . . . and cannot be
    introduced.
    The motion judge concluded plaintiffs' experts could "talk about life plans, but
    they cannot talk about $75,000 or $91,000 as in the baseline for plaintiff's
    economic loss as that is speculative." In a written order the motion judge
    directed that Provder and Kucsma were "permitted to testify about the life plan"
    but were "barred from testifying or using $75,000 or $91,000 as the
    measurement of wage loss to calculate future losses" because those figures were
    "not based on [p]laintiff's prior employment history."
    Hassan moved for partial summary judgment on plaintiffs' negligence
    claims against him, arguing plaintiffs had not plead sufficient facts to support a
    negligence claim given that they alleged only that Hassan acted with the intent
    to cause plaintiff harm by striking him. In opposition, plaintiffs argued "a jury
    could find that [Hassan] was guilty of both negligen[ce] and acting
    intentionally."
    The judge who had decided the motion regarding plaintiffs' vocational and
    economic experts granted Hassan's motion for partial summary judgment and
    dismissed all negligence claims against Hassan with prejudice. The motion
    judge found "plaintiff has failed to establish any duty or obligation [d]efendant
    Hassan had to protect plaintiff from injury or breach there[from]." The judge
    A-0222-20
    13
    held "[w]ithin the context of customer/employee relations, there is no such
    obligation imposed on an employee not to commit assaults on customers."
    Therefore, the motion judge found "no genuine issue of material fact that
    Hassan's conduct constitute[d] negligence." Plaintiffs and Hassan subsequently
    agreed to dismiss with prejudice the remaining claims against Hassan.
    III.
    In this appeal, plaintiffs argue the motion judge erred in granting Lowe's'
    summary-judgment motion, noting the motion judge did not address plaintiffs'
    allegations of negligent supervision and contending a sufficient causal nexus
    existed between Lowe's' alleged negligent training and supervision of Hassan
    and Hassan's altercation with plaintiff and that Hassan was acting within the
    scope of his employment at the time of the altercation. 7 Plaintiffs also appeal
    the order granting Hassan's motion for partial summary judgment, arguing the
    physical confrontation at issue demonstrates a failure by Hassan to exercise
    7
    Plaintiffs argue for the first time on appeal that California's enterprise liability
    standard of respondeat superior should be adopted and applied to this case. We
    do not reach that argument given that we for other reasons reverse the order
    granting Lowe's' summary-judgment motion and because plaintiffs did not raise
    it in the trial court. See N.J. Div. of Youth and Fam. Servs. v. M.C. III, 
    201 N.J. 328
    , 339 (2010) (finding that "issues not raised below will ordinarily not be
    considered on appeal unless they are jurisdictional in nature or substantially
    implicate the public interest").
    A-0222-20
    14
    reasonable care, Hassan had a duty not to commit an intentional tort, and, given
    the disputed facts, a juror could conclude Hassan's negligence caused plaintiff's
    injuries.   Plaintiffs appeal the order denying plaintiffs' motion to bar the
    testimony of Lowe's' biomechanical-engineering expert, arguing the expert's
    opinions were inconsistent with physical evidence, flawed because the expert
    had not conducted recreation experiments and had not interviewed witnesses,
    were net opinions, were not beyond the ken of an average juror,
    mischaracterized testimony, or were otherwise inaccurate. Finally, plaintiffs
    appeal the order precluding evidence regarding plaintiff's lost earning capacity,
    arguing plaintiffs' vocational and economic experts' opinions were supported by
    plaintiff's work and earning history.
    In response, Lowe's argues the motion judge correctly granted its
    summary-judgment motion because Hassan was not acting within the scope of
    his employment when he assaulted plaintiff and, thus, Lowe's could not be held
    vicariously liable for his actions; and plaintiffs failed to establish Lowe's was
    negligent in training or supervising Hassan or that any such negligence
    proximately caused the altercation. Lowe's contends the motion judge correctly
    denied plaintiffs' motion to bar testimony from Lowe's' biomechanical-
    engineering expert, asserting the expert was qualified and that his opinion had a
    A-0222-20
    15
    sufficient factual basis and would be helpful to a jury. Lowe's argues the motion
    judge did not err in precluding plaintiffs' vocational and economic experts from
    testifying about plaintiff's lost earning capacity because their opinions were
    speculative and not based on the evidence.
    Lowe's cross-appeals the orders denying Lowe's' motion to bar the
    testimony of plaintiffs' retail-industry expert, granting plaintiffs' motion to
    exclude opinion testimony from the responding police officers, and denying
    Lowe's' related reconsideration motions. Lowe's argues the motion judge erred
    in not barring the retail-industry expert's testimony because his opinion was a
    net opinion, he improperly relied on Lowe's' internal policies, and the subject of
    his opinion was not beyond the ken of an average juror. Lowe's argues the
    motion judge erred in barring the police officer's opinion testimony about how
    the incident occurred because their opinions are based on their perceptions and
    observations pursuant to N.J.R.E. 701.
    Responding to plaintiffs' appeal of the order granting his motion for partial
    summary judgment, Hassan argues the motion judge correctly determined the
    facts cannot support a claim of negligence against Hassan.

    We review a grant of summary judgment using the same standard that
    governs the trial court's decision. RSI Bank v. Providence Mut. Fire Ins. Co.,
    
    234 N.J. 459
    , 472 (2018). Under that standard, summary judgment will be
    granted when "the competent evidential materials submitted by the parties,"
    viewed in the light most favorable to the non-moving party, show there are no
    "genuine issues of material fact" and that "the moving party is entitled to
    summary judgment as a matter of law." Bhagat v. Bhagat, 
    217 N.J. 22
    , 38
    (2014); see also Grande v. Saint Clare's Health Sys., 
    230 N.J. 1
    , 24 (2017); R.
    4:46-2(c).
    "An issue of material fact is 'genuine only if, considering the burden of
    persuasion at trial, the evidence submitted by the parties on the motion, together
    with all legitimate inferences therefrom favoring the non-moving party, would
    require submission of the issue to the trier of fact.'" Grande, 230 N.J. at 24
    (quoting Bhagat, 217 N.J. at 38). We owe no special deference to the trial court's
    legal analysis. RSI Bank, 234 N.J. at 472.

    453 N.J. Super. 358
    ,
    379 (App. Div. 2018). Courts have recognized "but for" and "substantial factor"
    forms of causation. Komlodi v. Picciano,

    "But for" causation applies in cases involving "only one potential cause of the
    injury or harm." Ibid.; see also Evers v. Dollinger, 
    95 N.J. 399

    (finding in "the more routine tort case . . . the law requires proof that the result
    complained of probably would not have occurred 'but for' the negligent conduct
    of the defendant").    "Substantial factor" causation applies "when there are
    concurrent causes potentially capable of producing the harm or injury." Ibid.;
    see also Brown v. U.S. Stove Co., 
    98 N.J. 155
    , 171 (1984) (finding "a tortfeasor

    Negligent supervision and training "are not forms of vicarious liability
    and are based on the direct fault of an employer." G.A.-H. v. K.G.G., 
    238 N.J. 401
    , 415 (2019). To prove negligent supervision or training, a plaintiff "must
    prove that (1) an employer knew or had reason to know that the failure to
    supervise or train an employee in a certain way would create a risk of harm and
    (2) that risk of harm materializes and causes the plaintiff's damages." Id. at 416.
    The motion judge granted Lowe's' summary judgment on plaintiffs' direct
    negligence claims against Lowe's because he determined "proximate cause does
    not exist."    He made that determination even though "[g]enerally, the
    determination of proximate cause is an issue of fact for the [factfinder]." Cruz-
    Mendez, 
    156 N.J. at 576
    . "Only in the rare case in which 'it appears to the court
    highly extraordinary that [the actor's conduct] should have brought about the
    harm,' will courts remove the issue of proximate cause from the jury." 
    Ibid.
    (quoting Caputzal v. Lindsay Co., 
    48 N.J. 69
    , 78 (1966)); see also Broach-Butts
    A-0222-20
    19
    v. Therapeutic Alts., Inc., 
    456 N.J. Super. 25
    , 41 (App. Div. 2018) (requiring
    court to apply the highly-extraordinary standard when determining the actor's
    conduct was not the legal cause of another's harm).
    The motion judge erred in granting summary judgment as to plaintiffs'
    direct negligence claims against Lowe's on the basis of his determination that
    "proximate cause does not exist." Even if the judge had applied the highly-
    extraordinary standard in determining as a matter of law that "proximate cause
    does not exist" – and he didn't – the record evidence would support sending the
    question of proximate cause to the jury. Viewing the facts in a light most
    favorable to plaintiffs, a reasonable factfinder could conclude Lowe's knew of
    the importance of training new customer service associates to interact with
    customers, including unhappy customers questioning whether the customer
    service associate knew what he was doing, to ensure a "positive customer
    experience" and of pairing a new customer service associate with an experienced
    associate while still in training. Yet, despite that and contrary to industry
    standards, Lowe's assigned Hassan to work alone and unsupervised in the
    department before he had completed his training. It was for the jury, not the
    judge, to determine whether Lowe's failed to train and supervise Hassan
    A-0222-20
    20
    properly, and, if so, whether that failure was a substantial factor in causing the
    harm at issue in this case.
    2.
    The motion judge also erred in granting summary judgment on plaintiffs'
    vicarious-liability claim. "The imposition of vicarious liability upon employers
    for the acts of an employee, also known as the doctrine of respondeat superi or,
    is based upon the idea that the employee is the agent . . . of the employer." G.A.-
    H., 238 N.J. at 415. "Under respondeat superior, an employer can be found
    liable for the negligence of an employee causing injuries to third parties, if, at
    the time of the occurrence, the employee was acting within the scope of his or
    her employment." Carter v. Reynolds, 
    175 N.J. 402
    , 408-09 (2003).
    Courts have considered four factors in determining whether an employee's
    action is within the scope of employment. Davis v. Devereux Found., 
    209 N.J. 269
    , 303 (2012). An employee's action is within the scope of employment if:
    (1) "it is of the kind he is employed to perform"; (2) "it occurs substantially
    within the authorized time and space limits"; (3) "it is actuated, at least in part,
    by a purpose to serve the [employer]"; and (4) "if force is intentionally used by
    the [employee] against another, the use of the force is not unexpected by the
    A-0222-20
    21
    [employer]." 
    Ibid.
     (quoting Restatement (Second) of Agency § 228 (Am. Law
    Inst. 1958)).
    "The question of whether an individual acted within or outside the scope
    of employment often arises in the context of intentional wrongful acts of the
    individual employee that the corporation disavows in order to avoid respondeat
    superior liability." Vosough v. Kierce, 
    437 N.J. Super. 218
    , 235 (App. Div.
    2014). An employee's intentional or reckless action may be considered within
    the scope of employment. Id. at 235-36. As our Supreme Court recognized in
    Davis, "[w]hen the employee's conduct – however aggressive and misguided –
    originated in [an] effort to fulfill an assigned task, the act has been held to be
    within the scope of employment." 209 N.J. at 303; see also, e.g., Gibson v.
    Kennedy, 
    23 N.J. 150
    , 154-57 (1957) (holding evidence supported finding that
    train conductor, who had testified he was acting in self-defense, was acting
    within the scope of his employment when he struck a passenger); Mason v.
    Sportsman's Pub, 
    305 N.J. Super. 482
    , 489-500 (App. Div. 1997) (tavern's
    bouncer, who testified patron had hit and threatened him, was acting within
    scope of employment when he injured patron); Schisano v. Brickseal Refractory
    Co., 
    62 N.J. Super. 269
    , 275-76 (App. Div. 1960) (holding employee could have
    been acting within the scope of his employment when he hit the plaintiff). "The
    A-0222-20
    22
    fact that the employee's conduct is intentional and wrongful does not in itself
    take it outside the scope of his employment." Vosough, 437 N.J. Super. at 236.
    When an employee's assigned duties "place the employee in situations in
    which physical consequences may follow in an uninterrupted sequence from
    verbal exchanges with third parties[,] . . .     [i]t is a question of fact what
    motivated an employee's conduct as verbal exchanges escalate or when an
    employee's use of physical force becomes more pronounced."          Restatement
    (Third) of Agency § 7.07 cmt. c (Am. Law Inst. 2006). "An escalation in the
    pitch of an employee's conduct does not by itself transform the conduct into an
    independent course of conduct that represents a departure not within the scope
    of employment." Ibid.
    When an employee's actions are "so far removed from the scope of his
    duties," the employee is not considered to be acting within his scope of
    employment. Vosough, 437 N.J. Super. at 236; see also, e.g., Davis, 209 N.J.
    at 306-07 (finding counselor's premeditated act of throwing burning water onto
    a patient was not within scope of employment).
    Hassan's actions are not "so far removed from the scope of his duties" that
    the motion judge could decide the issue of vicarious liability in a summary-
    judgment motion.     Unlike Davis, this case did not involve an employee's
    A-0222-20
    23
    premeditated attack. Under either plaintiff's or Hassan's factual scenario, the
    altercation began with an employee performing his job in his assigned
    department by interacting with and providing information to a customer, the
    employee and customer engaged in a verbal exchange, and that verbal exchange
    escalated to a physical altercation.          Whether that escalation transformed
    Hassan's actions into "an independent course of conduct" outside the scope of
    his employment, see Restatement (Third) of Agency § 7.07 cmt. c, or whether
    his actions were unexpectable by Lowe's under the circumstances, Davis, 209
    N.J. at 303, was for a jury to decide.
    3.
    The motion judge erred in granting Hassan's motion for partial summary
    judgment. In Brill v. Guardian Life Insurance Co. of America, 
    142 N.J. 520
    (1995), our Supreme Court summarized the "essence" of a court's "inquiry" in
    deciding a summary-judgment motion:             "whether the evidence presents a
    sufficient disagreement to require submission to a jury or whether it is so one -
    sided that one party must prevail as a matter of law." 
    Id. at 536
     (quoting
    Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 251-52 (1986)); see also Vizzoni
    v. B.M.D., 
    459 N.J. Super. 554
    , 567 (App. Div. 2019).
    A-0222-20
    24
    Here, the evidence is not so one-sided that Hassan is entitled to prevail as
    a matter of law. Genuine issues of material fact clearly exist based on plaintiff's
    and Hassan's differing views of the altercation and what led to the altercation.
    The record contains sufficient evidence to support a jury finding that Hassan
    intentionally assaulted plaintiff. The record also contains sufficient evidence –
    including Hassan's own testimony – to support a jury finding that Hassan acted
    negligently in inadvertently striking plaintiff while attempting to block
    plaintiff's punch. Accordingly, whether Hassan's actions constitute negligence
    or an intentional act should be decided by a jury, and not a judge in a summary-
    judgment motion. 8
    B.
    A trial court's decision concerning the admission of expert testimony into
    evidence is entitled to our deference and is reviewed under an abuse-of-
    discretion standard. Townsend v. Pierre, 
    221 N.J. 36
    , 52 (2015). An abuse of
    discretion occurs when a judge's decision "was not premised upon consideration
    8
    The motion judge stated in his decision: "[w]ithin the context of
    customer/employee relations, there is no such obligation imposed on an
    employee not to commit assaults on customers." It would seem self-evident that
    at a minimum a store employee has an obligation not to assault the store's
    customers. Even if it wasn't self-evident, Lowe's' Workplace Violence
    Procedure makes it clear that assaulting a customer could result in termination.
    A-0222-20
    25
    of all relevant factors, was based upon consideration of irrelevant or
    inappropriate factors, or amounts to a clear error in judgment." Masone v.
    Levine, 
    382 N.J. Super. 181
    , 193 (App. Div. 2005); see also State v. S.N., 
    231 N.J. 497
    , 515 (2018).
    N.J.R.E. 702 and 703 frame the analysis for expert-testimony
    admissibility. Townsend, 221 N.J. at 53. N.J.R.E. 702 imposes three basic
    requirements:
    (1) the intended testimony must concern a subject
    matter that is beyond the ken of the average juror; (2)
    the field testified to must be at a state of the art such
    that an expert's testimony could be sufficiently reliable;
    and (3) the witness must have sufficient expertise to
    offer the intended testimony.
    [Landrigan v. Celotex Corp., 
    127 N.J. 404
    , 413 (1992).]
    See also Townsend, 221 N.J. at 53. Those requirements “are construed liberally
    in light of Rule 702’s tilt in favor of the admissibility of expert testimony.” State
    v. Jenewicz, 
    193 N.J. 440
    , 454 (2008).
    Pursuant to N.J.R.E. 703, an expert opinion must be based on "facts or
    data derived from (1) the expert's personal observations, or (2) evidence
    admitted at the trial, or (3) data relied upon by the expert which is not necessarily
    admissible in evidence but which is the type of data normally relied upon by
    experts in forming opinions on the same subject." State v. Townsend, 186 N.J.
    A-0222-20
    26
    473, 494 (2006) (quoting Richard Biunno, New Jersey Rules of Evidence 896
    (2005)); see also Townsend, 221 N.J. at 53.
    Rule 703's corollary, the net opinion rule, "stands for the proposition that
    an expert opinion must have a rational basis" and prohibits admitting an expert's
    opinion into evidence if its conclusions are not supported by factual evidence or
    data. Crispino v. Twp. of Sparta, 
    243 N.J. 234
    , 257 (2020). "[T]he net opinion
    rule requires an expert witness to give the why and wherefore of his expert
    opinion, not just a mere conclusion.” Jimenez v. GNOC, Corp., 
    286 N.J. Super. 533
    , 540 (App. Div. 1996); see also Crispino, 243 N.J. at 257.            "[B]are
    conclusions, unsupported by factual evidence, [are] inadmissible." Buckelew v.
    Grossbard, 
    87 N.J. 512
    , 524 (1981); see also Fin. Servs. Vehicle Tr. v. Panter,
    
    458 N.J. Super. 244
    , 257 (App. Div. 2019).
    The net opinion rule does not impose a "standard of perfection."
    Townsend, 221 N.J. at 54. Rather, it "is a prohibition against speculative
    testimony." Grzanka v. Pfeifer, 
    301 N.J. Super. 563
    , 580 (App. Div. 1997). A
    judge should not admit expert testimony "if it appears the witness is not in
    possession of such facts as will enable him to express a reasonably accurate
    conclusion as distinguished from a mere guess or conjecture." Vuocolo, 
    240 N.J. Super. 289
    , 299 (App. Div. 1990). However, an expert's testimony should
    A-0222-20
    27
    not be excluded simply "because it fails to account for some particular condition
    or fact which the adversary considers relevant." State v. Freeman, 
    223 N.J. Super. 92
    , 116 (App. Div. 1988). The net opinion rule does not "mandate that
    an expert organize or support an opinion in a particular manner that opposing
    counsel deems preferable." Townsend, 221 N.J. at 54. That an expert declines
    "to give weight to a factor thought important by an adverse party does not reduce
    [the expert's] testimony to an inadmissible net opinion if [the expert] otherwise
    offers sufficient reasons which logically support his opinion." Rosenberg v.
    Tavorath, 
    352 N.J. Super. 385
    , 402 (App. Div. 2002). Instead, the purported
    deficiencies in the expert's opinion may be "a proper 'subject of exploration and
    cross-examination at a trial.'" 
    Ibid.
     (quoting Rubanick v. Witco Chem. Corp.,
    
    242 N.J. Super. 36
    , 55 (App. Div. 1990), modified on other grounds, 
    125 N.J. 421
     (1991)).
    Under that legal framework, we see no abuse of discretion in the motion
    judge's denial of plaintiffs' motion to exclude the testimony of Lowe's'
    biomechanical expert. Dr. Fisher opined about the trajectory of the grout bag
    and dispersion of grout and set forth the factual bases for his opinions. As the
    motion judge correctly held, Dr. Fisher's expertise was "outside the ken of the
    average juror and [his opinion] is not a net opinion." Plaintiffs' arguments
    A-0222-20
    28
    regarding purported errors in Dr. Fisher's report and criticisms about what Dr.
    Fisher should have done provide the bases for cross-examination, not the
    exclusion of Dr. Fisher's testimony. As for Dr. Fisher's comments regarding
    whether plaintiff's or Hassan's testimony is consistent with his conclusion s
    regarding the physical evidence, we are confident the trial judge and trial
    counsel will be mindful of the long-standing rule that experts may not opine
    about the credibility of witnesses. See State v. J.R., 
    227 N.J. 393
    , 411 (2017);
    State v. McLean, 
    205 N.J. 438
    , 453 (2011).
    The motion judge abused his discretion in barring plaintiffs' vocational
    and economic experts from "testifying or using $75,000 or $91,000 as the
    measurement of wage loss to calculate future losses."
    In a personal-injury case, an "injured party has the right to be compensated
    for diminished earning capacity." Caldwell v. Haynes, 
    136 N.J. 422
    , 433 (1994);
    see also Donelson v. DuPont Chambers Works, 
    206 N.J. 243
    , 258 (2011).
    Diminished-earning-capacity damages are based on the plaintiff's lost wages and
    "include[] the value of the decrease in the plaintiff's future earning capacity."
    
    Ibid.
     The plaintiff must present sufficient factual evidence from "which the
    A-0222-20
    29
    quantum of diminishment can reasonably be determined." Coll v. Sherry, 
    29 N.J. 166
    , 176 (1959).9
    The vocational expert set forth the factual basis for using $75,000 as the
    measurement of wage loss to calculate future losses:             plaintiff was a
    "construction supervisor" for the last two businesses for which he had worked
    or owned and $75,000 is the average earnings of construction supervisors in
    plaintiff's county. The economist used $75,000 based on the vocational expert's
    finding. The experts, thus, set forth the "why and wherefore" of their opinions,
    Jimenez, 
    286 N.J. Super. at 540
    , and the motion judge erred in striking their
    testimony as net opinions. Defendant is free at trial to challenge the experts'
    opinions, arguing, as it does in this appeal, that plaintiff never actually earned
    that amount and likely would not earn that amount. But, again, that is the basis
    for cross-examination, not a finding of a net opinion. 10
    9
    Because the "proper measure of damages for lost income in personal-injury
    cases is net income after taxes," Ruff v. Weintraub, 
    105 N.J. 233
    , 238 (1987),
    parties may present evidence regarding what a plaintiff's net income was or
    would be, including evidence of a plaintiff's income-tax obligation. Caldwell,
    
    136 N.J. at 434-36
    .
    10
    The parties' dispute about the $91,000 figure apparently is not based on any
    finding or opinion of plaintiffs' experts, but on plaintiff's testimony concerning
    his earnings. Again, defendant is free at trial on cross-examination to challenge
    the credibility of that testimony. The motion judge's reliance on Bell Atlantic
    A-0222-20
    30
    The motion judge did not abuse his discretion in denying Lowe's' motion
    to bar the testimony of plaintiffs' retail-industry expert. Balian explained the
    factual bases of his opinions, and, as the motion judge correctly found, Balian
    demonstrated sufficient experience in the retail industry to qualify as an expert
    in the field, he stated his opinions were based on industry standards and
    practices, and the standard of care required for training and supervising retail-
    industry employees is beyond the ken of an average juror.               On cross-
    examination, defendant may challenge Balian's understanding of industry
    standards or its training materials, but, again, that is not a basis to exclude his
    testimony.
    Finally, the motion judge did not abuse his discretion in barring the
    responding police officers from testifying about "their opinions of how the
    incident occurred." The judge did not by rote bar their testimony but expressly
    held the officers could testify about "any factual issues that they observed,
    including plaintiff's demeanor, [being] evasive with answers, defensive,
    arrogant, and the like." His ruling is appropriate under the circumstances and
    Network Services, Inc. v. P.M. Video Corp., 
    322 N.J. Super. 74
    , 101 (App. Div.
    1999), a business dispute with "enormous complexity of the multiple business
    relationships" and "new, highly innovative products whose reception by the
    public was doubtful," was misplaced.
    A-0222-20
    31
    consistent with the law. See McLean, 
    205 N.J. at 460
    ; Gonzales v. Hugelmeyer,
    
    441 N.J. Super. 451
    , 460 (App. Div. 2015). The police officers did not witness
    the altercation between plaintiff and Hassan. To allow them to opine as to how
    the altercation occurred would be a clear invasion of the jury's factfinding-
    province.
    IV.
    In sum, we reverse the orders granting Lowe's summary-judgment motion
    and Hassan's motion for partial summary judgment and the order precluding in
    part testimony from plaintiffs' vocational and economic experts. We otherwise
    affirm.
    Affirmed in part; reversed in part and remanded for proceedings consistent
    with this opinion. We do not retain jurisdiction.
