1. ATP-PC system last for 10 seconds, but your body does not "transition", ATP-PC just becomes a secondary system beyond 10 seconds. Instead, the more dominant Anareobic Glycolysis system takes charge. During Bolt's 100m, his splits slow beyond the 80m mark, representing the change of dominant system at around 8 seonds. Bolt runs the 100m using ATP-PC ≈ 95% of the time. The graph YOU SHOWED literally shows the crossover between Anaerobic Glycolysis and ATP-PC at 6 seconds, but ATP-PC depleting at 10 seconds.
2. The power system chosen by the body is depedent on heart rate, and not how fast you are running. Example: ATP-PC is used beyond 95% maximum heart rate. In the 200m, it is not neccesarily going at "maximum speed" through the bend, but rather going at maximal intensity to stay with the other runners. Anyone who has run the 200m knows that you cant magically turn on the ATP-PC system on the straight after jogging the bend. Yes, the bend mechincally limits the speed, but that is not relevant since the bend is equal to each runner.
3. When you do any sort of excerise, it is NOT one system that does all the hard work, as you claim, instead its a combination of all three working simultaneously, at different dominances. Example: beyond 10s, Anareobic Glycolysis becomes the dominant system. At the instant the race begins, you are still technically using Glycolysis and Aerobic, but extremely miniscule amounts of it.
If I am wrong, let me know please! I dont want this to spiral into an argument I just want people watching this video fully understanding whats going on.
