100% positive that TR mobile app receives total power. Here you go:

> Just went outside for a two minute test… at 40 seconds I unclipped left shoe and pedaled with only right foot as seen here in Garmin Connect: ^ that was recorded on Garmin Edge 530 Now lets see what TrainerRoad app on iPhone recorded… I pressed record on Garmin at same time as starting TrainerRoad… and TR has 5 second countdown and so its 5 seconds behind: Both are showing 116W at the same time, and there is no power being applied to left pedal. Conclusion: TrainerRoad is…

Last night I was outside doing a workout and then did some single leg drills. It definitely takes at least 10 seconds for the Stages to recognize that I’m only pedaling with the right leg and start sending power/cadence data (to my Garmin 530). Believe the post above also shows (BLE to TR app) a delay from the time you start pedaling right-side only, and the time the Stages starts sending power/cadence data.

Garmin 530 recording from last night’s 5-minutes of single leg drills, where it took ~5 seconds to unclip and switch legs:

Notice the long pauses without power/cadence? Its like the Stages “gets confused” and takes a short amount of time to realize I’ve gone right side only. Annoying.
