First minutes of Wrist HR is always way off.

Wrist HR detection seems to be better that in the past now. But what i am really wondering about is that it always takes at around 10-20 Minutes for the watch to get the wrist HR correct. After that it proves that it is able to get a correct HR - but why not from the beginning?

This is from an on water rowing activity.

Here a little bit of running.

How long are you going from the waiting for GPS screen, to starting typcially, right away? maybe try waiting a bit longer to allow the high power mode HR monitoring to happen... before starting the ativity. bit of warmup before can help also to get HR up a bit so watch isn't freaked out trying to 'catchup to a rapidly rising HR'. So walk with a few lunges, or shoulder scrunches or clench biceps etc for a minute or two before starting.

Your row graph, I can understand a few mintues to lock on to BPM although you had a nice low HR warmup row so thought it should lock quick, but the run is just ...slow/bad reading.

This problem is also in activities without GPS (indoor). In the session above the waiting for GPS screen where there for several minutes (started the rowing-program when preparing the boat)

As an example here is the HR from an indoor rowing session. Even with this sessions i stay on the waiting screen before starting for several minutes:

I know, rowing is very difficult to monitor with a wrist HR monitor. Before the latest updates which were intended to fix the HR-Problem (which also enabled the recording of wrist har simultaneously with the belt-received HR) it was impossible to use the wrist HR for any rowing activity. So it became better - but i really can not understand why the sensor is not able to get the correct HR for at least 10 Minutes when starting any activity.
