Well I tried it, but it seems that my takings on BTC is about half that of other pools although I do have additional NMCs. Not sure if I am purely unlucky or not. Will try it again and do another comparison.
You didn't respond me my questions about possible connection issues or higher stale rate. If your connection doesn't have any serious troubles, then it's just a luck. Thanks to
calculations done by cosurgi, pool is performing as expected in long term, so I don't worry about bad performance in last two days (yes, it was lower than it should be, it's without a debate).
