I think I know what you are after. You want to know your speeds at certain markers on the track. The best way to do it is:
1: Note what kind of track you are riding (250 vs 333 style).
2: Note that your speed goes up in the middle of the turns. So, for a F200M on a 250M track, you'll see 2 speed spikes: One at the 200M start line in turns 1-2 (your fastest of the event) and one in turns 3-4. If you are on a 333M track, you'll have 1 speed spike that happens in turns 3-4.
3: Take relative measurements from those markers. On a 250M track, roughly 12" after that first speed spike is your entire 200M. On a 333M track, 6" before and 6" after that speed spike is your 200M event.
You can do the same as above and work backwards and see your speeds during the windup. You can spot your jump out of the saddle when your speed goes from steady-ish increase to spiking sharply.
Here's an example of a F200M on a 250M track using SRM software for analysis:
Note the 12" interval that was sectioned off after the event. He starts it at the top speed and ends 12" later.
We have the benefit of seeing the green power spike when he launched his attack. But, even if we didn't, we can see his speed dramatically increase at the same moment. So, we don't need
power to see when the "jump" takes place.
