Don't know, you might try asking on the Westside Barbell Instagram or Youtube pages. Louie Simmons and those guys handled his training for a few years early 2000's. The answer sounds flippant to me, like he was guessing or just throwing a number out there. If he did hit 25 x 275, you've also got to wonder about the quality of the reps, were they short-stroked, etc....?
It sounds off, but he was an elite wrestler and MMA guy, plus we don't know what the reps looked like, and he was heavier sometimes, #230ish.
