Does anyone know how Garmin is calculating its "average distance" stat? I can choose a club and manually calculate the average from all of my scorecards and DOES NOT equal the "average" Garmin gets...often, it's not remotely close. Is Garmin just bad at math or is there some method in their calculation that isn't obvious? To state the obvious, if the "average" isn't the average, isn't this totally useless?
