I just added Stress Score, a few weeks back, to my spreadsheet for run data tracking.
So far, I don't see clear-cut correlation between lower or higher morning SS score and faster(or slower) times on 5, 8, or even 10+ mile runs.
With regard to Recovery Advisor, it doesn't seem to be cumulative for the full days exercise. If I run 10+ miles, and it says "14 hours" recovery. Then, right after, I cool down with a 1 mile walk, it will say "1 hour" for full recovery. Am I interpreting it wrong?
