All payouts are retroactively calculated, I'm currently just making a minor adjustment because due to a mistake I made in my scripts some of the bonus blocks were calculated twice and I would end up paying more than the pool has!
You can see partial progress on my pool https://dig.coinage.ro/index.php?page=statistics&action=blocks where it's actually at the last block found by the pool.
Bonuses are not show in the Amount field yet but that will be fixed soon as well!
Unfortunately php and mysql work very slowly together to calculate the payments everyone will be getting so it takes a lot of time to update for so many blocks!

UPDATE: I think I've finished, waiting for pool to retroactively calculate all payouts (will take at least 1 hour... took 1 on my pc and it's better than the server)
