Those whose counting is wrong, you are in group A and you have rates of Group B, right?
I think you perfectly!
@fokysss as I am in good faith, I say what the error is.
Me my downloads are in group B (a majority France) but when I saw others say it is not good I calculated the ones I and the result is that I get for 0.012$/DL for 700Mb files, which normally corresponds to group A.
So the rates are simply reversed. If you want to check on my account send me a PM.
