i think, he meant 50.650.000 and 50.000.000.
yes, there is a slight difference here.
before the formulas had been changed, it was always level^3 times 15 xp for every level. back then, nobody was over level 100.
when the first players came close to level 200, it started to be too much xp per level. we didnt want to change the low levels needed xp but also wanted to have a nice level number, where we change the formula to a linear one. that was first level 100 and later, level 150, because 100 seemed to be too low
