Deleting activity doesn't reduce load, intensity minutes, recovery time, nothing (Physio TrueUp broken?)

By the way, where is Physio TrueUp toggle on the watch itself? I can't find it on the Fenix6 watch itself, or the android app.

Only the online version of garmin connect has Physio TrueUp toggle under the device general settings?

But anyway, so why in 2023 after years of development across many previous Fenix generations, when you delete an activity, none of the FirstBeat metrics are recalculated?

The watch is left with the previous load the deleted activity generated, the intensity minutes the deleted activity generated, the recovery time the deleted activity generated?

None of that makes any sense. It should all be recalculated when activity deleted (or added)

Basically my HRM belt failed, went to 220bpm and stayed there and the Fenix6 just decided that was real and possible and maxed out everything.

So also why in 2023 does Garmin firmware decide that 220bpm is real when the maxHR is set to 180bpm and 220 is a known HRM fail mode?

No human being on the planet can sustain 220bpm for a minute certainly never half an hour.

Why does Garmin not block HR data over max HR ?

Guess I'll have to file this again on the next beta firmware if there is one.

  • That was my intent.  I think because the PM connected to the HU first, it just never connected to the watch (don't know why -- it can be flaky).  I do the same thing when I ride in zwift (start an "Indoor Cycling" activity on the watch concurrent with the Zwift sesion), because I don't find that I get the intensity minutes correct otherwise, since most of the time wrist HR isn't very accurate while riding a trainer (so I have my watch connect to my chest strap).  I then don't save that watch-initiated activity when I'm done -- it's exclusively used to ensure I get accurate HR during the activity for the firstbeat metrics that are calculated on the watch.

  • I would rather suggest doing it in the opposite way - only recording all with your watch, keeping just that activity, and not using the HU, and also not syncing Zwift to GC at all. You get the most accurate and the most complete metrics from the watch (assuming the HRM and the power sensor are connected to it too). 

  • The problem is until the Fenix6 series and beyond, there really wasn't enough computing power/ram/storage to do all that reshuffling/recalculation on the watch.

    The HRM-Pro download feature after activity to correct for ANT/BLE broadcast lost (which can be significant at times) is actually pretty impressive feature.

    But it still does not correct all the metrics on the watch itself if the downloaded data is signifiantly different than the original broadcast. 

    It is very buggy because it's so underdeveloped

    Here's a bug example where a run was changed from Tempo to Base effort after the activity because the HR data was significantly different, yet it does not change the effort in the weekly totals or the load distribution graphs elsewhere,  forget syncing it with Garmin Connect online

    In theory they could streamline this by doing more in their cloud online afterwards and then pushing it to all your watches in their ecosystem but of course that doesn't help people out on the trails with no online-connectivity.
