Xp requirements to level

[Morsakin]

The way it's coming up with the amount needed per level is to use the L^3 x C x R x H to find the total xp at the end of a particular level, and then subtracting the value obtained from the previous level to find the difference, e.g. how much XP you will need to pass through said level.

So if total XP at end of level 2 = 5,000 and total XP at end of level 1 = 1,000 (Just for an example) you'd need 5,000-1,000 = 4000 XP for level 2.

Another way of looking at that table is instead of thinking End of Level "X" it could say 0% into Level "X+1"

As for more than 11% / kill, I don't think that's meant to be possible? Could be wrong but I seem to remember getting exactly 11% on alts back in the day when killing mobs much higher in level.
