I'm not sure what your graphs show. Since you are riding on unloaded rollers with a, presumably, high cadence it could mean that you just got more efficient at spinning on the second day. It doesn't look like you were putting out much power so it's not clear what the purpose of the workouts was other than to improve your spinning technique.
