Battle Rank XP Calculation

[SerethiX]

My Question is not directly API related, I just wanted to know, if there is an algorithm SOE uses, to set the XP borders.

I could simply copy the values from the wiki, but thats not exactly how I want to solve problems ;-)

I already tried using algebra, but my function puts out negative values between 1 and 5.

So I could say its not directly a*x^2 - b*x + c
anyone know how this works??

My obsession is to know the current BR of BR 100+ guys ;-)
