For PDGA events they need to make this model the standard...
Everyone in the group gets a scorecard.
Everyone keeps everyone's score (in the same name order on all cards)
At end of round everyone compares everyone's scores.
This way you make sure there is no cheating.
All players in group have to go to the TD after round and turn in one card that is correct.
And it makes it easier for the TD to check cards, because there should not be any errors in scoring as the group just checked all 3-5 cards to makes sure everyone has the same score.
I have seen this used a few times and it is the only way you can stop people from cheating.
Hard to beat this setup. :thmbup:
