You make a tremedous number of assumptions that don’t actually meet up with scientific observations. For example, you again talk about faster sprinters having shorter GCTs because of some mechanical difference in their form…it just isn’t so. Faster sprinters have shorter GCTs because they are running faster. If you have data or film, look at GCTs of sprinters of different caliber when running at the same speed. You will find scatter with little correlation. I don’t mean to be an arse, but long winded diatribes that consist of opinon and anecdotal observation without any science to back it up doesn’t go very far on this forum.
