I am sure one of the if not THE reason we use those forms is for liability waiver. If we would instead have every club furnish one of those to the state office for every competitor before a card could be issued I think we could get away from it. You would obviously do away with the weight indication and simply indicate the age and date of birth.
These type of situations that doug747 describes are called "correctable errors". These types of errors can be corrected without being detrimental to any other wrestler or causing harm in any way. I don't understand, we will hold up the start of tournaments for hours so we can change brackets for all those who didn't make weight, and cause long term harm to our sport by doing so, but we don't correct the few errors that cause none!
