I have blamed my HR monitor or strap before when the readings were (temporarily) wildly off (like 240 bpm). But THIS TIME I had a separate monitor (a FITBIT which also monitors HR but does not use the Garmin strap). And it was also reading the same odd #'s as my Garmin and it does generally read the same #'s (roughly) as my Garmin. So in this case I believe the #'s (where in other cases I didn't but I also didn't have a 2nd HR monitor system in place).

BTW, I have never encountered a long connection delay with my Garmin strap and Edge device.
