It's worth pointing out that a decent ref won't be giving many cards to players 13 and below. Regarding U14 thru U16, most of the cards given will be in the top league to players with academy ambitions. At younger ages there is a sliding window in terms of tolerating minor infringements (i've been seen to demonstrate a throw in, rather than penalise foul throws), but this doesn't extend to disciplinary offences. Cards to age ratio reflects disciplinary offence to age ratio, but YC/RC decisions can't be discretionary based on age
