In addition to skill level mastery, I track and grade my students' total learning minutes on a weekly basis in order to promote continuous skill improvement. In the past this was useful due to the "average response" calculation. It seems now Khan is recording "screen time". I now see absolutely no work completed yet up to 43 minutes of what I call, "Effort" minutes.
My question is... Is Total Learning Minutes a resource you use? If so is this skewing your data as well? If so again, how have you managed it?
