I don't think we can change the limit from 5 to 3 rates right now, since that would make things really unfair for the teams who participate in the next round. If you want to change, then you should change it from Round 7, when every teams have reached their third round.

(Personally I don't think it's necessary to change, since 5 rates is the standard and accurate rating number for me. But oh well, it's up to you to decide)
