After about 30 miles of baseline testing, I'm having trouble validating my OEM dynamics. Between crosswinds and traffic, getting good data is a nightmare!

Even so, it looks like I have way overestimated the baseline rolling resistance which is closer to 82W per mile per hour. Cd was looking closer to 0.34, but with a sustained 90 degree crosswind kicking 10-15 mph right now.

Apparently I'm going to have to go out at 3 AM to get good measurements.
