Thank you!
You raise a good point that measuring air density plays an important role in making sure the CdA measurements are solid.
We do measure it continuously, and incorporate it into the calculation. But what we don't like is when storm fronts come in in the middle of a run. It's the quick transients that hurt. We've also tested *a lot* at the VELO Sports Center. Maybe 20,000 laps. And we see our Stig runs, that keep coming in at the same CdA +/- 0.8% when we're careful.
