@TheMountainRabbit For me is the other way around, the hrTSS matched but the rTSS never matched.
I’ve double checked the settings between the watch and TPs multiple times, both pace and HR. There is no reason for such difference.
Never got any proper explanation here and, and by the lack of other comments, I thought it is a “me” problem.
So, I stoped caring about it.
TBH, I’m considering TP my “Source of Truth” so I don’t care want the Suunto App says anymore.
At the end of the day, it’s just a number. The important stuff is the training and the effort you put in it.
