As far as TD's watts using .217 CdA, .004 Crr and other generalizations like 3 secs for turning/etc and a slight 2mph quartering crosswind it matches spot on with his time of 4:11.

TD = Tom Danielson .

follow the link to saris for the video.

Sort of makes me think of jockey's on the ponies. There would be no chance of 200lb guy getting that small on the bike. http://ibikeforums.com/posting.php?mode ... a5f329a654#

Yes, I think that was his TT position, correct?

yes, TT position , numbers in the screen shot that are cool are the 2cm increment moves up or down on stem and the resulting change in cdA as measured in the wind tunnel.
