how about recruiting account 2 on account 1 , and , account 3 on account 2? still get 300% XP?

the thing is i did the same but i think it is taking a little long. i have a full 5-man group which looks like this, with a boosting lvl 80 character (account 1):

account 1 RAF'd account 2
account 2 RAF'd account 3
account 3 RAF'd account 4
account 4 RAF'd account 5

for example i got 2 levels (for each character obviously) from 30-32 by doing a run of SM armory and library. does this sound like i am getting triple XP?
