Good to have something to start from though and there are exceptions to every rule.
I wouldn't count a 1st place with only one kid in the bracket either, I think I saw somewhere that it should have no less than 4 wrestlers in a bracket to count. I also think with 6U there are probably more exceptions than other ages.
Another issue what if they are meeting and beating the same kids at every tournament due to their age & weight being short on wrestlers to get those 1st place spots should those types of 1st count??
