Then we did a ride indoors with the 90km and 800m climbing. At the end she was 16km behind. She averaged 28kmh and me 34kmh.This is what I dont understand.
I'm not surprised that your Rouvy average speed was higher. Perfectly still weather, smooth roads, optimised virtual aero position etc. But it does sound like your wife wasn't getting any draft in Rouvy. That would be the first thing to check. Draft Wattage should show above here avatar.
Have you tried swapping trainers?
Edit: Since she finished 16 km behind, obviously she got no draft!
