my cards are easy to add up, multiply the number of targets shot times 5....20X5=100 easy......
as for the punching, i have seen it done many ways. i am a puncher, and if i make a mistake i initial and circle. i agree that if the cards are not punched by the time they get to the scorers table they need to be. if the clubs overlook it, the door is open to mischief.
