[...] I believe for absolute fastest leveling boosting just one character is the fastest, although adding more doesn't slow you down significantly; probably around the order of 20 or 30% longer with 4 alts instead of 1 [...]
Before RAF 3x I made some experiment in stockades and found I got the most xp with 1 high level and 3 lowlevels; 1-1, 1-2 and 1-4 were all lowers than 1-3; so typically when I ran my alt I tried to get 2 other lower level to tag along for max xp

I'm not sure how that plays with the 3x which probably now dwarves the grp bonus (unless the grp bonus is also multiplied by 3 ?)
