Quick question. It seems current lap data isn't part of the activity info data via API.
If so, in order to calculate "Current Lap Avg Power" I'd have to save the Avg Power at the time the lap button is pressed and the moving time. And then, during the lap, look at the updated current avg power and moving time. And then determine the lap power required to cause the change in the overall avg power.
Ugh. would be nice if current lap data was available via API.
