Calculate recovery score for calendar and wellness tab

I’m searching around, if I can calulate recovery score for calender and wellness tabs.

In the wellness tab I currently have this chart. Based on an existing chart of intervals.icu


Is it possible to anyhow calulate the relation between base and normal? To get 0-100%

I searched through the forum and I found reference to api and java. API should be able to do the trick, but I want to avoid it. I prefer intervals.icu integreated functions so everybody can use it.

I use IMReady4 for this. How to Guide - ImReady4 app, for HRV guided training

doesn’t let me log in, despite correct username and password. A bit strange. I’ll try again tomorrow as I’m currently locked out
