Big Bang Level EXP Curve

Behold my Excel (Open Office Calc, actually) skillz, noobier than even Nexon's:

How many kills of monsters the same level as the character are needed to level up, before and after BB?




The pre-bb data points are few and far between because (a) I'm lazy and (b) people don't really train on mobs their level.
The points I use for pre-bb assume training at MP3, Windraiders, Gallos, Skeles, and Oblivion 4 as sort of anchors.
The under-50 data is kinda meaningless since everyone CPQ's, but I only thought of that after entering it...
Highest level mob before BB is 131 and after is 166, so of course higher level characters can't train on mobs their own level.
