@Egika adding my N of one, I also find it measures consistently different from every other watched I’ve used (a few from COROS, Garmin, and other Suunto watches, the Vertical 2, Race S, and Race). More telling, though, is those other watches all measure very close to my measuring wheel. The Race 2 measures shorter than my wheel, so in my experience, the Race 2 does indeed measure short. Thanks for your help on this!
