I'm confused about where the second screen shot comes from, but I think you're showing basically the same as what I was seeing.

• If I look at the STEEM/SP of a post before payout time, the number of STEEM/SP matches up with the displayed payout value in dollars.
• However, if I look at what actually gets distributed, the value of the rewards is off from the post value by the haircut percentage.

Here's a an example after payout time with no beneficiary rewards in play.

At the haircut price, $6.20 is about 24 STEEM. At actual dollar value, it's about 36. The actual rewards seem to match the haircut price.

Which means the actual dollar amount of the distributed STEEM and SP would be closer to 2 * $4.05 = $8.10. Similarly, it looks to me like your second screenshot probably matches the STEEM/SP distribution, but not the dollar value. The dollar value of 42 STEEM is in the neighborhood of $7.14, not $10.93.

No idea how I have never noticed this before. It's a substantial difference. Or maybe I just forgot, but it seems like something I would have remembered. Or maybe I had overlooked it due to the previous inclusion of TRX values.
