I have a question on #7, mainly because I use a cal course that I consistently get 4-5 clicks more in one direction than the other. For example I'd get something like:

4500
4504
4501
4504

So is that OK because the rides in the same direction are only a click or so off, or do the all the rides have to be within a click or 2?

Paul Hronjak and I theorized about the various reasons. Clearly it had something to do with the cal course being slightly uphill in one direction, downhill in the other, but exactly why it would cause that effect we never nailed down. In any case he accepted the measurements because the rides consistently gave the same directional error.

Flat spots long enough (and safe enough) to put a cal course on a few and far between around here, and my experience has been courses with even a slight elevation change will yield different measurements in each direction.
