Hi Andy.

The sum of my users' classes or leafs rate would not be equal to the
parent's. They will never add up to the total root class since I will be
adding rules every once in a while so, if my root total BW is 15Mbps and
I have 100 users at 512kbps each then, that could be a problem. 

Is there something else to do instead?
