Sense Heart rate accuracy

Hi everyone new user here. My question is how accurate is the heart rate monitor on the Fitbit sense as I've seen a number of articles stating how inaccurate it is. Has this issue been fixed with software updates? Had the apple watch 6 previously but it's so bad that I had to send it back

Just updated to the latest firmware, heart rate during running exercise spiked up to about 20BPM in the first five minutes of my run then stabilized the rest of the way with a few hiccups on the Sense in keeping up with the heart rate reading of my armband strap. Trying not to let it bother me too much and just take the Sense's metrics at face value. 

 

That's the main reason for getting an armband heart monitor anyway relative to the Sense's HR readings.

To measure HRV accurately, you first have to measure heart rate accurately,
and I don't think there is any doubt that the technology used by a Polar
chest strap is far more accurate then the technology used by the Sense (or
most other wearables).

That is my complaint also.  I will start a workout on the Sense and walk at a very casual pace, maybe 3 MPH, and the Sense will record a heart rate in the 120 to 140 BPM range and after 5 to 10 minutes it settles out to what I would expect in the 80 to 90 BPM range.  I tried to contact, via email, FitBit over this and got a robo-reply back that the email is not monitored.  Using the chat feature is not much better and all the chat 'bots do is return canned responses.  No way to contact the developers for bug reports, performance improvements, suggestions, beta testing, etc.  The survey that shows up now and then is populated with pre-canned questions and answers.  Especially bad when one has 20 years of medical device development experience and another 20 years of aerospace development experience.  Crickets.
