Has anyone seen their max heart rate be adjusted after using the unit for a while, or should I just adjust it now? I don't have a super reliable estimate for Max HR, but I'm pretty sure it's higher than what is set. If the unit will adjust it, I'll be patient, but I don't want to be waiting for a cat to bark 8-).
thanks!
