*(this is exactly what I need for y <= x)

When I try to invert it, I get something like this, which is incorrect..:

(1-x / y+1) * (y / a * b)

So an example would be (1-52000/75000+1)*(75000 / 260000 * 65000)

(and this is too high for y > x)

Thanks, and sorry to trouble you. I just spent two days trying to resolve this and was (some freaking how) unable to.

I must have forgotten a lot of math.....
