It's because the price of STEEM is below the haircut price (~$0.104). Payouts are reporting wrong.
Roughly, to get the actual payout, the value shown needs to be multiplied by the 3-day average STEEM price divided by the haircut price (i.e. ~0.04/0.104).
The reported price is only accurate when the STEEM price is above the haircut price.
Ok, I think I understand. Thanks
