Our local course has 18 permanent holes and 3 temporary holes. During PDGA sanctioned league, 3 of the permanent holes are typically unavailable because of youth football practice. So, for league we play 15 of the permanent holes and the 3 temporary holes. Today, youth football practice was cancelled and the group in front of us tee'd off on Temp Hole A. While walking to the basket, they noticed that youth football wasn't going on so they picked up their discs (without putting out) and went and played the 3 permanent holes that were not being used for league. While putting out on the last of the 3 permanent holes that weren't being used, we saw them and informed them that they had played the course incorrectly. They finished putting out and proceeded to play the rest of the permanent holes in order. So, they never finished putting out on Temp Hole A and they never played Temp Holes B & C like they were supposed to. The rule book doesn't describe how to handle a scenario like this. There seem to be several rules violations. 1) They picked up their discs and didn't hole out on Temp Hole A. 2) They played 3 holes that were not being used during the 18 hole league round. 3) They never played Temp Holes B or C (like the rest of the competitors). How many stroke penalty should be assessed to their final scores? Should they be DQ'd and their rounds not counted since they didn't play the same course as the rest of the competitors? Any insight would be helpful. Thanks.

Applicable Rule: 803.03.G.7
Incorrect Hole. The player has completed play on a hole that is not part of the course for that round, in place of a hole that is part of the course for the round. The hole shall stand as played, and two penalty throws shall be added to the player's total score.

So count every throw they took. Add 6.

Thank you!

Would you also add in the practice throws on the hole they were supposed to play but didn't hole out on?

The new rules explicitly state the misplays are not to be counted as practice throws.

However I would say that in addition to the shots taken on the 3 incorrect holes + 6 you also have:
803.03.G.3 Failure to hole out - for Temp Hole A (so however many shots they took + 3)
&
803.03.G.6 Omitted hole - for Temp Hole's B&C (Par + 4 for each)

No. You definitely would not count the omitted holes, nor would you stroke for failure to hole out. The 3 incorrect holes that they played count as holes played for the round and replace the other holes with the misplay penalty (+2 for each hole). I was referring to the throws taken on temp hole A before they moved on and played the other 3 holes.

Sorry, you're right about the omitted.
Thinking through it again they have played the following:
15 correct holes
1 correct hole without holing out
3 incorrect holes

So you could count one of the incorrect holes as an Extra hole (2 shots, none of the strokes) and include the failure to hole out in the 18.

Frankly it's such a spectacular balls up you're better off counting it as DNF

Wouldn't this earn you an 888?

I would throw those scores out completely. You don't want to give them inflated handicaps if you use handicaps.

I meant the TD should bin it.

If they were shooting a really hot round, they might still be above their rating after adding 6 strokes. The TD should definitely NOT bin it as that could have a material impact on the round ratings for other players. Also, the players deserve the penalty strokes for playing the course incorrectly. They should have paid attention.

As for a league handicap, it is always a good idea to have a system for throwing out sandbag rounds to prevent anybody from having an inflated handicap (and to prevent unpleasant accusations). In the handicap leagues that I run, anything 12% over their average is tossed out regardless of reason.
