Thanks, everyone, for the education. Bob, I do clamp the brake, as you taught me long ago. So it should all even out over 4 or more rides, as you say, so I won't sweat it.
Apropos of nothing, I guess, it is interesting that we use a different logic in establishing a working constant than in using a Sum of Shortest Segments measurement. That is, we do not select either the longest or the shortest calibration ride count. Rather, we use an average of at least 4 good rides. I mention this because by strictly using the same logic as SSS, wouldn't we assume the cal ride with the lowest count total to be the most accurate ride?
Of course, a smaller working constant would result that way, which I assume is one reason we use an average instead. Is my thinking on track?
