hi,
i have my 735xt set to 25 metres, as i swim in a 25 metre pool, and today the watch measured at least 12 extra lengths. i swam approximately 60 lengths and the watch measured 72. i did not have this problem 4 days back, so it could be a bug introduced due to some recent update
here's my swim, where it can be clearly seen how erratically the lengths were measured: https://connect.garmin.com/modern/activity/1512364406
sofware version being 7.10
anybody else encountering this? any explanations?
demonstrating the problem in attached screenshot:
