XP scaling table

Anyone have more info about how insane the scaling/diminishing returns of XP is to reach lv100?

IRRC it took 2-4days for ladder to be filled with lv91-92 char?, and that's during first playthrough, i'm sure if 2nd char it can be done in 2 days.

HOWEVER, i see the ladder is still not filled with 100's after one month, so i'm going to imagine the 95 or 96 --> 100 is insanely hard?

Anyone at lv97? 98? 99? can chime in to tell how many avg xp u get per 1 basic lv80 maps? Not xp/hour as that's useless info - too many variability in build, but xp per one full clear on a basic map...
