TSS has changed dramatically in last few weeks
-
My calculated TSS’s have gone down dramatically in the last few weeks. For the same exercise, despite similar heart rate and time of exercise, the TSS has gone down by about half. Either the old ones were way too high or the new ones are way too low. Anyone else have this problem lately?

@kludwig Have you checked your zones were not changed during an update?
You can also check it against a free TrainingPeaks account.
-
@kludwig Same here. I can more and more sports but it goes down.
But tomorrow my vertical 2 will arrive. I’ll see if it’s different there. -
Same here. Suunto support confirmed that they are working on the issue. Hoping this will be fixed in next updates.

@kludwig check HR, power and pace zones.

I wonder how one is supposed to know what their power zones are? Most people know how to figure out their HR zones, although many still do it incorrectly. Pace zones are more difficult but can be derived from race results or a lactate threshold test. Personally I wouldn’t know if I didn’t have my lactate threshold pace from Garmin. But power zones? No idea at all how to get these right?
I think if Suunto algorithms depend on zones so much, there has to be a guided test in the watch to calculate the zones - a guided test that does everything end to end, including updating the times.

I’ve updated my power zones using my last 10K Race (december) data amd using a external tool. Now the 3 zones are more aligned for flat running (in trail running pace will differ).

@jjpaz I use TSS
for trail running all the time, and that seems to produce results consistent with TSS(hr).
In fact my TSS
values tend to be a bit higher. That makes me think that grade adjusted pace (NGP) is actually used in relation to pace zones when it comes to calculating TSS.I tend to ignore power zones because I am not used to them and as I don’t know how to calibrate them. And from what I know running power numbers vary a lot from rand to brand, which makes me not trust it. It has been at least a decade since I’ve run a road race. I guess I could look at some threshold efforts to see where my power stabilizes. That works be close to the threshold power.
