Good data there.

The major variable in coefficient of friction will be the road surface. If one calibrates on a concrete road, and measures on asphalt, the Cf will be off. Assuming there's a significant difference between the two.

If you really want to get pointy-headed, calibrate on asphalt and concrete, and note which portions of the course are which surface.

As far as slipping goes, I've ridden enough bikes in winter to say, you'll know when a tire is slipping.

I think the asphalt vs. concrete experiment bears investigating. Concrete is far grippier; will it yield a lower constant?
