@Mikey, i use the Polar Flow software and the M460 head unit to track recovery. The M460 has an Orthostatic test and records HRV trends, but im struggling to understand the method Polar use to determine if you’re recovered or not which is available after you’ve done 3 tests within 28 days. I just back off a bit when not recovered.
I’m 63 and use the 4 week model and also look at the trend on individual weeks to see how long i’ve been working in the zones.
