Reply to "Hilly calibration courses"

1. A calibration course can have an appreciable slope without affecting its accuracy compared with that of a flat course. Uphill rides however should be taken slowly. This conclusion agrees with that of Pete but not with that of Mark.

Neville,

I'm not suggesting that downhill rides or uphill rides have more variance than flat rides.

I'm suggesting that averaging uphill and downhill cal rides will not give you the same cal constant as averaging flat cal rides. Your experiment did not test that possibility.

The fact that you got more counts (or revs) for uphill rides compared with downhill rides is surprising. Clearly, the effect of hills may differ from rider to rider.
