Do you have a quote/link?

I found this from the designer on slowtwitch:

What kind of typical cruising speeds were you cycling at to get these results? 16, 18, 20mph?

We rode at a variety of speeds during our studies. Of course higher speeds produce lower yaw angles, but there wasn't a significant enough difference to worry about. What the overwhelming result was, no matter where we rode, is that yaw angles are typically much lower than we believed in the past. Our data shows that 50% of your time is spent between 0 and 5 degrees, and by the time you get to 10 degrees of yaw, you have accounted for 80%. You spend only 20% of your time between 10 and 20 degrees of yaw, and as the angles get higher, the percentage of time gets lower.

Long story short, what I've said above really holds true for the average speeds almost any athlete is maintaining.
