A bit of an aside, but from what I gather, does this mean there is no limit to the originating RAF account in terms of receiving gifted levels?

IE, If account X referred new accounts A, B, C, D and they all hit 60, can account X now be gifted two level 60 toons? 60 levels earned x 4 accounts (ABCD) / 2 (gift a level for every two you earn) = 120 giftable levels = 2 60s right?

Also, the blizzard page made it sound like RAF benefits end the moment any character on the new accounts (ABCD) hits 60. Does this mean if I want to maximize my benefits across multiple sets of toons, I need to temporarily stop at 59?
