Where'd you do this and when? Bogota? I'd say you were a pretty impressive sprinter in your time if you were doing under 10 seconds repeatedly, since the officially recognized world record is just over 10 seconds, I believe, and Harnett's sub-10 was taken at altitude, thus impossible to match at most tracks anyone here's likely to be racing on.

I hate to call BS (and I apologize for doing so if I'm off-base), but just want to point out that ZappCatt's times are pretty damned good, especially so for somebody who doesn't get out to the track that much and there's no reason to discourage him.

Not sure if anyone's mentioned it before but there's an interesting mathematical model of the flying 200 at analyticcycling.com; probably worth checking out if you REALLY want to plan your drop down point and trajectory.
