We used to hear a lot about Bolt and even CL, who had huge stride length.
Now we have CC, who went 9.76 in 47 strides.
Compare that to Gatlin at 9.89 in 44.25 strides, and that's with his short first step.
CC is a turnover monster, back to the old days of 47 strides for the 100m. His turnover never let up in Doha, same as SAFP.
Even ADG had about 46.5 strides, for bronze.
Hughes had about 45 strides to finish back in the pack.
For the first 6 strides, CC and Gatlin are identical, then CC edges ahead in both turnover, and distance traveled.
This is the key to his relentless speed development--and by that, I mean the continuous-ness of his acceleration. Some guys have better acceleration in certain phases, and worse in other phases, but CC is continuous. He has no hitches, no lags, no irregularities. His acceleration is consistent, relentless. The balance between his stride length and frequency seems to be perfect.
Collins was a guy who also had great speed development, but who would end up cutting his stride short in favor of turnover maintenance, and thus was never able to hit the type of vmax that CC and others can hit. IMO he was imbalanced in favor of turnover.
Gatlin, OTOH, has seemed to me to have been generally imbalanced in favor of stride length. In his Doha 9.74, he went about 43.5 strides -- 3.5 strides less than CC, and 0.02 faster.
Does CC still have room to improve, considering his eggbeater mechanics, by increasing his stride length in the second half of the race?

Coleman was not deaccelerating as badly from 85m to 100m in 2019 W.C.100m as badly as he deaccelerated over final 15m of 2017 W.C. 100m, but Coleman's rate of deacceleration is still worse than others. Of course he can improve, but Coleman will never be a strong finisher.

He also dopes like a fiend so your analysis is irrelevant.
Both dopers
Christian Coleman 5'9"
Justin Gatlin 6'1"
Carl Lewis 6'2"
Usain Bolt 6'5"
Relative to height they are taking nearly the exact same amount of strides.
