Just trying to be helpful. Lots of things out there to study. You may have to wait a while. Would there be any negative impact for you to record morning HR and SpO2?
So last year I was in the feed zone chatting about this same stuff with a mom. Her kid was a Cat 4 14 year old at the time.
They decided to use the same trainer and same methods. He's now a 15 year old Cat 2. Same stuff.
