Everyone gets a random percentage when they make their account which they can never change; the highest is 10 and I -think- (not sure) the lowest is 5. Mine is 6, but my friend's is 8. =/

The highest is 10. :P

There's no way to increase it either.

Mines 8, I didn't know it was different for each person!

Great, I got 5% ._. That's lousy Dx
