He looked down the entire test. If he had been looking up, maybe it would be closer.
I'm referring to data taken in the last year by the BBS aero analyzer of the United Healthcare team in which was trying to get real world CDAs to match wind tunnel CDAs. Some people were close and some were way off because they couldn't hold the exact position in the tunnel in which they were completely still with heads down.
I think my head position was in a realistic spot because I was staring at the tracings up ahead of me. I have tremendous head discipline in races, so much that I very often can't see up ahead of me.
What I couldn't do in real life is stay that tense. Trying to hold absolutely still makes you mad tense. Does moving around more and relaxing more and a bunch of other things IRL impact your "effective" CdA? Sure. But none of that is going to change the order of these frames, which is what we were trying to isolate as a variable in this test.
