Slush, you may have missed the post where Geebus said (even though FairUser kept saying otherwise for quite some time) that they are accepting stale shares (CurrentWork-1) for inclusion in the payout calculations.

This means that slow users with many *would have been* stales are still just sitting there, processing away at useless work for 5 to 10 minutes and yet still get paid from the proceeds of the solved block. This is great for CPU Miners because they are getting paid even though they are doing useless work.

But where is the money coming from to pay for this huge amount of useless *would be* stale shares?

It's coming out of the pockets/payouts of the fastest GPU Miners! Faster Miners are letting Slower Miners have a part of their proceeds even though the Slower Miners are processing useless work and weren't contributing to the success of actually solving the block.


So, that 5% penalty for so many *would be* stales isn't coming out of the pockets of the people that are actually getting the *would be* stales, it's coming out of the pockets of the people that spent money to have fast hardware and very few stales!!


With the change to pay stale shares, this pool went from being one of the best (payout-wise due to 0% fees) for extremely fast miners (say a 5970) that get can process the entire GetWork solution space in 10 seconds or less, to one of the worst (only ahead of Pay-Per-Share 10% fee pools) due to subsidizing the payouts of those with slower hardware and thus more *would be* stales.

Likewise, this pool went from being an absolute nightmare impossibility for extremely slow miners (like CPU or nVidia GPUs) to being better than the PPS 10% fee pools (unless there are only slow miners in the pool......), but still wouldn't pay out as much as a normal pool.
