The whole product, on one real case.
Three minutes on Cohen v. Luckin Coffee Inc. (S.D.N.Y.), the fabricated-sales case. Every screen is the working product on the public record: the extracted facts, a live event study on Luckin's actual prices, the four-part Exposure & Settlement Brief, citations opened at the page, and a live cross-examination of the opposing expert.
Narrated. Press play, and keep the sound on: the voiceover carries the analysis.
The same matter, with and without the simulation.
Retaining an expert is a single, late, indivisible decision: one expert, one reading of the facts, arriving on the disclosure calendar. Everything downstream is gated by it. A simulation separates the analysis from the retention, which changes when you see the other side's case and how many readings of it you can afford to test. The cost lines below are deliberately conservative: they use general-practice expert rates, and securities and antitrust engagements run well above them.
1. Fed. R. Civ. P. 26(a)(2)(D): expert disclosures are due at least 90 days before trial, and a rebuttal within 30 days of the other party's disclosure, unless the court orders otherwise.
2. Derived, not surveyed, and deliberately conservative. The ExpertPages fee survey puts the average expert witness rate at $465 an hour in 2026, up from $451 in 2024; economic and financial experts are commonly quoted around $425 an hour for analysis. A 25 to 30 hour opening workup falls in the band shown. That average spans every practice area. Securities and antitrust engagements, where the retention is an event-study econometrician or a damages expert, sit at the top of the distribution, so read the left column as a floor rather than an estimate. Your own engagement letters are the better number, and we would rather use them.
Supreme Mind figures are list prices. The two rows marked New have no equivalent line item on the left because the work is not something a retained expert is engaged to do.
