Yes, miners got a bit of a boost with credit on shares that should have been rejected, but that wasn't very fair to the pool or pw.
I disagree - I think the old system was quite fair.
phzi, we all know the real reason you think the old system was more preferable. It was because you purposefully overtuned your miners to submit as many shares as possible, regardless of whether they were valid, in order to claim more shares for yourself. You have already brazenly admitted to gaming the old more lenient system and essentially cheating fellow miners out of some of their rightful profits.
Not trying to take sides, but I do remember someone saying to set xintensity to 1100 on wafflepool but leave it around 300-400 on other mining pools because of the old system.
