I have not measured anything on mine, and don't plan to. But with 2500+ miles, the tires, chain, and sprockets show no unusual wear, and it handles fine. Finding things that are not straight that you can't really do anything about just makes you feel bad. I used to tell people with old cars that were still running good not to check the compression. They would probably find numbers they didn't like, and if it was running fine that's what counts.
