Danimal, I'm trying to explain why he was able to maintain that.
Cockysprinter- This is the generally accepted wisdom, however, I've yet to see anyone explain the physics as to wy this is so. If nobody can explain the physics as to why this is so, then perhaps we're operating off an incorrect model.
Also, Johnson, Greene, Ato, Crawford and Collins are all at around average height (at least for an American Male) within two inches. They are not "tall" in any sense of the word, as none of them touches six foot. only 60% of the olympic golds you put forth can really be considered "tall" and 60% isn't really a statistically significant amount.
And l specifically said "I'm not talking about stride length"
