Speed endurance the key to *all* 11/12second sprinters?

My 30m cam broke down in Paris GL but i estimate his time at 3.87. His reaction time was 0.174 (rounded up to 0.18), that gives 3.69 without reaction time. In Berlin WC, it was RT 0.146 (0.15) and 30m 3.79. That gives 3.64. We’re not talking over a tenth.

Sorry, i didn’t watch the vid till the end. It was taken in Bruxelles GL, probably 2 days before the race. I timed the 100m in the bend circa 11.00 FAT. His best time in the bend beeing 9.92, this is 90% pace. We don’t know how much time rest there was between reps, probably 5min as they seem to chat a lot. BTW the coach doesn’t say the workout is at intensive pace, this is your interpretation of it. This is sub max workout to me, in order to prepare his first competition after WC and get rythm through the curve. His race in Bruxelles was a submax competition, 19.57 is at least half a second slower than his projected best.
