Let me put it right:
The completion %% is meant for mulitplayer games. Therefore, a CC tournament played as a single and interrupted or restarted does not count in.
Furtheron, Alternate Shot games don't count in AFAIK, because the odds are too relevant that another player would be the cause.
This leaves MP strokeplay. matchplay, Blitz and Skins to be in charge for the %%.
Unfortunately, these games have been quite instable for too long, and apparently some users know how to interrupt the games and turn possible losses into wins.
