One other piece of advise, is to have someone or maybe both carts record a full score card of the round. At the end sit down and verify that both score cards, or a combination of both the score cards and your personal record match what you have. Then transfer the scores to the official upper section of your sheet.
This will help to eliminate any questions or concerns by turning in a clean (No scribble/erase free) score sheet.
It also helps if you unfortunately run into a player who thinks they can shave points by erasing/changing their scores on a hole after your have signed and given the official score sheet to them… Which I have run into before. (Said but true but it has happened)
