I don’t, and that’s the reason I’m not using it…
I only use HRV rmssd, HR rest and the Baevsky Stress index.
All subjective scoring is done in Intervals Wellness.
Training intensity guidelines are based on:
- HRV and rHR charts on the fitness page (those are using the HRV4Training principle)
- ImReady4 app (based on iThlete Training Guide)
- Always prioritize your own subjective feelings if they don’t match the above.
For Baevsky Stress index there is a scaling available which might help you in your scoring.
