Flound, does your pool take into account stales when choosing which coin to automine?
For example on
http://coinchoose.com/ its showing Worldcoin at 160% but only 108% after stales.
Yes, my calculation docks WDC by 25% and DGC by 20%.
From what I've seen, we get around 10% orphans and the pool efficiency hovers between 90-95% on Worldcoin. So I'm hesitant to dock it by more than that. I probably would, if I had gotten any complaints about payouts being low (which I haven't.)
DGC efficiency is a bit higher and has fewer orphans.
