Reply to "ARE CALIBRATION COURSES UNNECESSARILY LONG?"

What a fascinating discussion, sorry I missed it when it was going on. Kudos to all for your input.
I just returned from measuring 3 courses in Bermuda. I have scoured the island looking for suitable calibration courses, and 250 meters is as long as I have been able to find. I believe there are longer possibilities over by the airport but they would be really inconvenient and I would rather calibrate frequently. I think many places in the US face the same kind of limitation.
I always keep track of spokes when I calibrate (haven't yet converted to decimal rim markings), and by interpolating between spokes I have a precision of 1/360 of a revolution. This is enough to know whether my calibration results are consistent or not. When I notice the differences aren't as consistent as I'd like, I sometimes make an on-the-spot decision to do some more rides. Not very scientific but I think it works pretty well.
