@mcneese.chad Yes, there are two basic cases:
- Erg mode
- Erg mode with power match (either Wahoo, or TrainerRoad)
In classic Erg mode, the trainer is responsible for:
- receiving target power from the app
- estimating current power
- making changes to resistance
With Wahoo “Control w/ANT+” all that changes is the trainer is getting current power from another source. In this case, just like classic Erg, Wahoo is completely responsible for controlling the resistance of the trainer.
TrainerRoad’s PowerMatch is different of course, as now TrainerRoad is responsible for controlling the trainer resistance. And to the trained eye you can see it struggling to do that, from time to time. But it generally works well.
