per-connection-classifier

I have a problem with per-connection classifier feature that doesnt divide packets into equal streams. I have 4 PPPoE accounts with per-connection classifier 4/0, 4/1, 4/2, 4/3. I surely remember that I had the connections being equally devided with a trick I made but I forgot it.. lets say i have 16 connections. 6 of them will go to account pppoe 1 and 6 to pppoe 2 and 2 to acount 3 and 2 to acount 4. I think the problem with the version of routeros but now i only have the newest version. thanks

So you have, 6-6-2-2 streams, which is equal to 3-3-1-1, which is in total 8. So, you can imagine the rest.
