Just got my 830 from the holidays. It has the latest upgrade (V5) installed. I paired the trainer and re-rode an outside course just fine. It shows up on Strava like an outside ride with the course map albeit classified as a virtual ride. Now, can someone tell how the heck does the 830 calculate the speeds when re-riding an outside course on a trainer? When I put out more power, it didn't go faster, so it is obviously not power driven like it would be in Zwift, Rouvy, BKool, etc.
