I might be wrong, but this is the breakdown I've got for the 2009 playoffs...
Round 1: 6/44 OT (13.6%)
Round 2: 3/14 OT (21.4%)
Total: 9/58 OT (15.5%)
Game 1: 1/12
Game 2: 3/12
Game 3: 3/12
Game 4: 1/10
Game 5: 1/5
Game 6: 0/5
Game 7: 0/2
Better pick your spots, cause so far these games have been finishing in regulation time.
