In any case, I wouldn't worry about anything with the powermeter for the time being. Just go out and ride, do some efforts, look at the data post ride, then go again. After a few weeks you'll have some data, a better handle on what that data actually means and relates to, and possibly how to use that data to plan for future workouts/goals.
