Agree with all that has been said. Without a bit more detail from over the winter and now, it almost looks like there is a gap between what you have done in training (known) e.g. 30m and what you will do/are currently doing (150s, 120s, 100s), MaxV (counting accel in distance) will help cover this as well as helping better MaxV.
IMO getting intermediate times over the race distances would help pinpoint where time is being lost; if you believe in something like Dick’s Sprint Control tables that 11.46 should have the athlete capable of the 22.9 you want but the “odd” number is the 60m time, it should be better than the 7.32 you mention and to attain 11.2 that much more so.
Danny pretty much covered it.
I did notice that too. I guess, I would employ testing over 30m along with flys or timing certain points a race. I would be that the acc is slower than what it should be which is delaying when he’s in max v. Which obviously over 60m if he’s taking 40m to get up to top end then he’s only at 20m max. He’ll be fine racing against lesser talent, but missing one or both of those phases will really be exposed at a bigger meet. I would imagine the best part of his race is 40-70m, but the worst part is 0-40m. The more time you lose up front the slower the time will be.
