By RAFing 4 new accounts to an existing account, you end up with one character not 'earning' the levels the other 4 are. You'll need to start 5 RAF accounts if you want a total of 10 new characters and take advantage of the granted levels.

A = ORIGINAL

B-F = FIVE NEW ACCOUNTS.

Daisy chain them so A<-B<-C<-D<-E<-F, with the arrow showing where the 'granted' levels will be going to. B-F would be your first five characters (1-60), then you level A-E for your second set of characters(1-30), then use granted levels to take them to 60.

You can then xfer 5 of those characters to your other 5 accounts.

If I understood you correctly that is...
