@underground Got it. Looked into payouts again and how quickly I forget. I've figured it out (again). Here's an example: say the payout that shows is $12. 75% goes to the author and 25% goes to the curators, so the split is $9 and $3, respectively. The $9 payout to the author is split 50/50 in SP and SBD, $4.50 each.
Since the SBD was originally pegged to $1USD, you receive 4.50 SBD and $4.50 worth of SP. Assuming the avg price of STEEM was trading at $6 during the earning period of your post, you would get 0.75 SP (4.50/6). So the final payout you would receive from the post is 4.50 SBD + 0.75 SP. I think there are other factors that go into the final payout numbers, but this is general idea of the payout structure from my research.
@colinbrazendale If SBD was trading at $1USD as it was intended to be, you would have received 8.22 SBD and 8.22 STEEM, but since SBD is trading around $6 you are actually making more in USD than originally intended. Assuming a $6 price in SBD and STEEM, your approximate payout for the post in USD is around (47.21 * $6) + (8.22 * $6) = $332.58.
