Completely Broken HR Sensor

So, the Wrist HR Sensor was never perfect, but it was OK after a few updates after the release.

But a few days from now, I'm getting completely broken readings during my runs.. Its drawing straing lines, with ~20bpm higher than it should.

I is broken since 5.10 or 5.30 release. Not sure, cause I just did one run on 5.10. It's like my 3rd run and its just not even close to be reliable.

A few days ago I was "top 20% of my age and gender". Now with these retarded readings and wrong HR I'm on top 30% already, after 2-3 runs. Completely unreliable. More broken than this forum new version.

Already restarted my Watch a couple of times.
