Congrats from 800.000 ;->
Level 100 was reported to be at 2.268.312 XPs, level 112 = 5.308.064 XPs. The stepping seems to be rather constant, a tad more than 250.000 XPs per level from level 98 until then, but further...?
FWIW, my numbers of the day are
1200 ranked rounds and
2000 forum posts exceeded ;)
