There's nothing to sort out. All these complaints about rewards are either a result of variance on slow miners, or bad luck with the designed score reset. There are no real problems. Everything is working the way it's designed.
Which is why nothing is getting sorted out.
When there is a real problem, slush will make an appearance.
If that would be the only glitch I saw last days OK. But this is not a case. I'm seeing missing shares(log from cgminer), jumping from stratum to stratum2, stratum3, api, backup pool(log and shares on backup pool)... And I don't see it fixed. Because of some random errors I got less on about 7 to 9 blocks now. Others have problem connecting... I think that Slush took a holiday without internet or something happened to him and pool is degrading without maintenance. So yes it is a problem... Slush didn't make a appearance over a week. This is not normal for him.
EDIT: and even if you are right that this is how it should work, why did Slush fixed this in a past?
