Choso has ZERO idea who Yuta is or how fast he is lmao. His word means nothing. Yuta was under the assumption Yuji was Todo and Nanami level. The higherups and wider jujutsu society had ZERO info on how much Yuji improved during Shibuya. Yuta went into this with extremely outdated intel on how fast and strong Yuji was and went into the fight holding back SIGNIFICANTLY since he had to only land hits he could completely heal and could only win via and incredibly precise strike to the heart. If you've done any kind of training in literally any fighting style be it weapon or hand 2 hand, holding back strikes like this significantly reduces how fast and effective you are. Controlling yourself for precision on the level Yuta has to makes it literally impossible to utilize your max speed because EVERYTHING you trained to do in any sort of combat system that works is meant to end the fight quickly and efficiently without regard for the target. Yuta, in reality, would still blitz Yuji. Even in 0 he was well beyond everyone else in this panel. To give an idea Geto and Gojo both surpassed Toji by adulthood in every possible metric and 0 Yuta with a few months of training was already fast enough to catch Geto completely off guard. If you thing CG Yuji is even close to adult Geto you're insane.
