Resources bug or?

[deliu b]

I observed that in the last weeks (or at least I started to pay attention) that the resources graph on suunto race watch doesn’t match with the sleep or rest, from previous day.
For instance if today I have 60 % resources and after a night of 9 hours of sleep of 82 % quality (data from sleep tracking), yes ended HRV was low, the second day the watch and app shows like i didn’t had any resources adding from previous day, even more I had one time saying that I lost 1% and another day/time 3% from previous day. How so? For me is not understandable.

It might be that if I reach 100% some variable in software is reseting to negative value? Also the yellow bars are missing, bars that are characteristics to deep sleep.
Then I can understand the negative resources as drop down from previous day vs current, where in between I had 9 hours of sleep.

Also I have reach like over 80% resources with yellow bars adding over the night I was surprised.

Did somebody had any issue with this parameter, or only in my case due to, maybe HRV condition?
