Most of my endurance rides are either done outside without power just HR or Rouvy on the turbo with power. Strava and Rouvy sync them to TR and I always complete the Rpe response afterwards Does AI Ftp take these rides into account when reassessing my ftp or does it just use TR indoor rides? My thoughts are that only those rides with power are taken into account but I could be wrong.
It does take those rides into account! Even those with HR alone.
It will, however, be more accurate the more power data it has.
