Not claiming any brilliance but I can think of one element that can HIGHLY confound the data collection. If I recall correctly, mavic mounted some or all of their instrumentation on the fork. And I think some of the other parties might have mounted some or all of their equipment on the frame, but with the instrumentation still located well ahead of the bike (so still in clean air).

Because even if the environmental conditions are identical, even the rider takes an identical path at an identical speed, and even if the instrumentation is set up in exactly the same place in space in clean air, just the change of fork vs frame mounting will give hugely different yaw data. When I saw that mavic did this, I wondered why in the world they would do this, especially if the point is to evaluate the whole bike + rider system ...
