Reply to "Why do we post-calibrate?"

Mark,

Yes, I missed that point. That is a valid point. That is the best reason for doing a post-cal for every measurement. Now, I can rest easy, knowing why we do something that rarely has an impact. (But, that is also why I ride airless tires.)

Oscar,

The problem is the "fat" tires. They do squish more in heat than thin tires. However, I have a measuring acquaintance that used to be quite large. He tried 700c x 20 airless tires. If it was "cold" (never below 45° where he measures), they were fine. But, when it got 75° or more, the tires squished under him. He quit using them. His measuring partner, though, a petite lady, had no problems with the thin tires. I don't, either. But, I measure almost exclusively in first-light conditions, so I don't get into hot measurements. I do one every couple of years, but that is it. The early measurer gets the best conditions. Wink
