My ratios with topbucks go from 1:500 to 0:3000 to 1:330 this period. I never seen such weird stats

Every pay period is different. If i dont get sales the first days of the month i know i wont get any till the 15th. Then the new period (16th) starts and my sales are superb again.
Im not bitching tho, they always pay but it does look kinda odd.
