I know this may sound an odd question, but what rate were we paid at? On the TX page, it says the payment was $ 72.50 ( 0.001818 ) for me and $ 80.00 ( 0.001999 ) for others at Legendary rank.
I know two of my posts were in the Off-Topic section, but what were the other two posts that were discounted?
I go by preev at time of finalizing sheets, sometimes swings have an effect (as well as what rate preev reports).
You do not get penalized based on your total posts, only if you don't hit the quota, at which point you get no payment. The rates are as per OP, $82.5 if you hit the bonus otherwise $75.
