Heart rate above 100 bpm is not calculated correctly

[TamerlanHajiyev]

Hello.

I am using my watch to get my heart rate data, and I see that whenever my heart rate exceeds 100 bpm, the outcomes become incorrect. Up to 100 bpm algorithm works fine. What is the range of values this algorithm works?

It seems like after 95-100 bpm real heart rate value, the algorithm converges around 70-80 bpm value. However, up to 95 real bpm value, algorithm's estimate is correct. I am using i7-1355U without gpu, if it is important. I am using simple_window.py.

I also updated all filter values to be between 0.7 hz (40 bpm) and 3 hz (180 bpm)

Hi, thank you for reporting this issue.
This is mainly a hobby project for visualization purposes and as such does not claim any correctness.
Most likely, this is due to the quite agressive signal filtering that is enabled by default. You could try to play around with the filter settings. See here for more details: https://samproell.github.io/yarppg/cli/
Change the values below to see if it produces better results.
