Battle Rank XP Calculation

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 ;-)

That is a dang good idea. Maybe send send a dev a tweet and ask? I'd start w/ Malorn.

Nice idea and good luck, but I doubt there's an exact mathematical formula.

I've tried and can rule out exponential functions (a*exp[b*x]) and polynomials up to the 5th order. It's definitely not an exponential function of any kind.
Anyway, I've made a plot of the XP needed for the next BR, so you can see how it roughly goes. Here it is:

That's actually two overlapping graphs, actual XP in red, fit in blue (5th order polynomial). I was too lazy to remove that.

Yes, i also tried different polynomials, but didn't get it to work to fit exactly the values provided in the wiki

I would guess its some kind of number series, not a trig function, based on all the numbers being multiples of 5... 25? I'd have to look again, but anyways, trig functions wouldn't end up like that, a series might.
