This is something I have known for a while, anyway AKA rates are not applied on accounts older than itself.
So lets say you have 15 different accounts.
One day on account #15 the newest one I hit 2k Accounts 1 thru 14 will not have my 2k AKA rate.
I haven't tested but i am pretty sure that if the next day on account 7 I reach 18xx accounts 8 thru 14 will have my 18xx aka rate and so on so fourth.
Just a fun little tidbit. I thought I would share.
