Holy Cow Batman - we do have some results. But before we get all excited, maybe we need to RETEST, just to see if the results stays the same (ie is the experiment is repeatable). Wouldn't hurt to tighten the test protocol so the numbers are the same eg. 26, 32, 36, 38, 40, 42, 44, max.
Here is the graph of the data:
Shows about a 12 watt reduction in drag at 40 kmh by using pink helmet, compared to orange helmet. And guess which helmet takes an additional 6-10 seconds in transition (ie get on your head)?
Now who wants to hazard a guess as to which is Limar Chrono 05 and which is Giro Advantage 2?
I'll post the answer tomorrow to allow some guessing time.
