I currently have 1 Veteran account and 3 "Slave" accounts, if i want to get the 3x exp on all four accounts, i do the following?

Veteran Account recruits New Slave 1
New Slave 1 recruits New Slave 2
New Slave 2 recruits New Slave 3
New Slave 3 recruits New Slave 4

Or can i just use my Veteran Account and recruit 3 new slave accounts?
The answer might already be in some thread, but there are so many threads about this now :P

[Edit] I tested number 2, worked. Now at level 10 with 1h 03 min played, time for RFC
