I was randomly wondering about the percent change in apparent CdA while drafting "normal" people at a "normal" drafting distance.
Instead, I found this dude's personal experiment with 2 friends riding a track. Idk if he was making this s*** up or not, because it's hard to believe.
He found a reduction of apparent CdA of ~0.033m2 (~30 watts) at 40 kph, 12 meters back. Lead rider was a small guy in TT position.
What do you think, possible or BS?
