However, on my local 333, it flips around, prompting me to think the 1st 100 is too slow. This is what got me thinking about playing with the line. Anybody else experience something like this?
It seems to me logical that starting the drop at the mid-point of T1-T2 (instead of the traditional drop point, a beat past the exit of T2) would do two beneficial things: One, it gives you the acceleration of the drop beginning, what 30-40m? before the 200 start line instead of 5-10 m. That would seem to be a good thing. Two, it gets you in the lane quicker and this shortens the true distance you ride for '200' meters.
Thoughts? I'd love to hear from people who've experimented with this.
I think it all has to do with the turns… its harder to hold down the power through a tight turn than it is speed.
on a 333m you only have to navigate 2 turns, and you get to sit before entering turn 3.. on a 250m track you need to sit while you are in turn 1- there seams to be an immediate power drop while sitting, (especially during a turn) despite the fact that top speed happens a bit later.. then you typically have a power burst on the back straight before you to enter turn 3/4 at high speed- but likely not being able to hold max power through the tight turn….
on a 333m you get to sit before entering the turn, ride through a much gentler turn, and i think it allows that second burst of power and speed to be more easily maintained.. =Negative Split
check this data from a flying 200 on a 250m track:
notice that power drops around the sit (the timed section is shaded) then speed peaks after(71kph)…
there is a peak in power on the back straight resulting in nearly peak speed being reached again as turn 3 is entered (70kph- probably peaked at the apex), but the power can't be held through the tight turn..
a small burst of power at the exit of turn 4 to fight off the inevitable slowing..
i think the speed graph would look more like an "Arc" and less like an "M" on a 333m..???
