I see that “export original” from Strava includes the Di2 data, however, I’m not sure if they are providing that data via their api download. If so, could it be added as a graph on the workout page? I do many of my workouts in non-ERG mode on the trainer or outside and might find some utility in knowing what gear ratio I was using during a previous workout and if I had to shift during an interval.
I realize that rides uploaded from Zwift and TrainerRoad to Strava won’t include that data as they have no functionality to connect to a D-fly sensor; it seems that only rides from a D-fly compatible device (Garmin/Wahoo/etc) would include that data in their original fit file.
EDIT: on thinking through this a little further, I’m not sure the best way to visualize the data in the graph. Di2Stats.com uses color codes for each gear combination and overlays it on the gpx route. Possibly a second graph with a line that changes colors at each gear change or draw the power graph with the color codes? It’s sounding more complicated as I think through and type this.
