Heart rate values from optical HRM still totally wrong with 20.26

Coming back from this thread, where a lot of us participated and gave valuable input, that you were asking for:

https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-955-series/362273/heart-rate-values-totally-wrong-after-update-18-22

With 20.26 this has NOT changed, it is still the same old bug.

This is an example from my usual bike commuting with just the watch and optical HRM, where it is way too low at the start and suddenly jumps up 50 beats:

Yes, you may contact me and yes you may have a look at activities in my account if it helps to identify the problem and yes, I live in Germany.

And PLEASE, don't just collect input again and then ignore us for weeks and months! Communication matters and seriously, the communication from official side here regarding the bugs (even the acknowledged ones) is more than poor.

It's off.

I will test pausing in a few days - because every example you provided was after training pause - you just pause or you select option to resume later?

This is not correct, some cases were wrong readings from the start.

I think there are several things to take into consideration. Garmin advises warming up before training to get accurate HR readings from the OHR, so I assume they know the algorithm they use is affected by this. On the other hand, after pausing an activity for an unknown duration, there is a noticeable error, as the algorithm is not able to handle these periods correctly. Here, I have redrawn the existing chart and split it into three different parts.

biggest error in hr is visible after pause period in that case

You are dreaming, there is completely different pattern.

Level of heart rate after pause is the same. 3 mins is enough to pump heart rate to working level.

how you know if its 3 mins or 20 mins?

There is a number at the bottom

Green and orange lines drawn by me are expected hr levels. What was unknown to me is pause time. Im only pointing out that.
1. before each training you should warm up
2. error seem to be bigger after pause than during warm up

Listen, you make too much assumption. According to you we should wear our watch at lab condition to get bearable result. I expect different from outdoor/multisport watch. And certainly I expect different level of communication, Garmin-Sierra

nope,

according to me there really might be some kind of bug that is triggered after activity pause - fixing it would clear 95% of error
