Systems, methods, and apparatus to facilitate the production and presentation of strokes gained golf statistics. Some systems include mobile devices for the collection of essential shot data necessary for producing strokes gained statistics during play. The device travels with a golfer, measures and records distance-to-hole automatically using GPS and/or laser and/or radio technology, in combination with one of various lie-type classifications (tee, fairway, rough, sand, green, recovery, penalty, hazards, etc.) before and after a golf shot as selected by the golfer using human judgement. The device transfers essential shot data to a remote database and receives and displays calculated strokes gained results.
