As I understand the calibration phase sets the baseline for the following meditation session.
So a calm % is relative to the way the calibration went
I do understand that this is a good thing to reward calming a busy mind down. Would the baseline be a default (Buddhist monk on a hill) than most user would be frustrated with their results.
BUT how about a rating of the baseline. This way the readings would be more useful and informative.
Example. I have all instruction voice.volumes muted and start to meditate while the sensor check and calibration. So my baseline is let’s say on a scale of 1 (calm) to 10 (busy) a 3 and I archive a calmness.level of 80% .
The next day I have a lot on my mind and my baseline score is 7 with the calmness level being again 80%.
Obviously the 80% in both cases is good compared to the baseline but has completely different values.
Maybe that is something a developer could think about.
It would be something I would like to see in the app and think it is useful to collect useful data to keep improving ones meditation skills.
