OK, I found out my RHR is more like in the low 60s if not lower. I sent some values to my Garmin device (edge 500) and see that my HR Max % is now based on the slightly higher max I input (188bpm vs the pre-set 185bpm). However my HRR% is still the same as my HR Max %!! Why is this?
Will the HRR % only differ at very high bpms? because even some jumping jacks really quick to get to 70% kept them both at the same percentage... intrigued.
