The 460 per hour is much more realistic than the 920. Of course it depends on how fast you play. For most casual players with several in your group I would say you probably burn less than 460. Of course if you play alone and run you would burn a lot more. I consider it a part of my exercise program. I also hit the gym and walk outside for exercise. I try to do something almost every day. Usually I play more than 18 holes at a time.
