Silly me, I can see your flag and yet here I am asking what ranking your local players are. No wonder you only mentioned your foreign players. Hahahaha.
That said, how do you get the breakdown on how much you earn via NT? I got mine from Justin so it was a one off thing xD Do you mean that in Monday, the figure will purely show the amount without NT, while if they play, the figure will factor in the NT appearance so you'll have an increase (hence the difference is NT appearance bonus)?
That said, I noticed that China is on top, Belgium is occasionally in the top 10 and never drops below top 20, while Serbia hovers around the 30s. Since all 3 of them earn you 9%, I assume the cut off point should be around 40-50, since your local players earn 13% while mine earns 11%. Despite Spain NT's rankings improving a lot over the weeks, you still consistently earned 13% because Spain did not drop out of the cutoff point. Should (hypothetically, fingers crossed, I bear no ill will), should Spain fall to the 50s or 60s, you might end up only earning just 11%.
