Utopian.io website shows the already released payout as 'Will release yesterday'. The grammar is not correct: Will release yesterday. See the following screenshot of Utopian.io:
On the other hand, Steemit.com can show this correctly. It shows 'Past payout $5.95'. See the following screenshot of Steemit.com:
Busy.org also shows it correctly and it shows the same information as Steemit.com. See the following screenshot of Busy.org:
Please note, for the same post
The reason is that in Steemit.com and Busy.org, it doesn't include the payout to the beneficiaries. On the other hand, Utopian.io shows the total payout including the payout to the beneficiaries.
Therefore, I believe, both Utopian.io and Steemit.com/Busy.org are acceptable in terms of payout amounts, though they show different amounts.
