I don't think "they" owe any of "us" anything. If they had an issue, it's been recognized, with help and diligence in testing, "they" should be able to return to the pool and be a productive contributor. If "they" had enough speed to bring the collective results down, without malice intent, with the appropriate adjustments, "they" can be just as likely to boost "us" back up. In the LONG-TERM more than making up for any "losses" as others may cast upon them, and benefitting us all.
Not correct. Even if they come back and find blocks, that doesn't make up for the lost income from the month they were mining. I'm still waiting for a response to my last email. While I'd love to see them return some/all of the coins they mined in the last month and then work out a re-distribution for those shifts (recalculate the shifts with their shares excluded), past experience with payout errors (0.8 fucking up the backend and crediting miners as if network diff was from 2009 and costing me 1200 BTC for example) have made me fairly jaded when it comes to that.
Of course, Minor Miner's numbers are also completely wrong since he's using a 3 month luck figure when we know for a fact that the only confirmed "bad miners" were only around for 1 month. Similarly, the assumption is that the pool luck would have been, at least, neutral without their influence, which is an assumption that has no basis.
