I was called in to be the BU on a 14U ASA FP game and the PU misapplied the CR rule. I found out about it after it happened and I tried to discuss it with him and he insisted he was correct and would not talk about it.
Both him and the UIC were incorrect so I went home after the games and double checked the CR rule to make sure I ws correct so that the next time I work with them I 'll have it available and will have it printed and in my pocket.
