Skins
Canadian = lowest gross + net. Net and gross use the lowest score of that kind. Pick None for no skins. Entry is per player. A tie wins nothing. "No par 3s" leaves the par 3s out of the skins.
Runs beside the first one with its own entry, pot and par 3 setting. Players have a separate box for each skins game.
Group vs group
Each playing group's best net scores per hole (100% handicap) against the other groups. Best 2 or best 3 of 4 count that many scores on every hole. Irish best ball counts 1 score on holes 1-6, 2 on 7-12, 3 on 13-15 and all 4 on 16-18. The winning group splits the pot. Entry 0 = standings only.
