I think i've might have fixed the issue that some rounds were skipped for certain users, it had to do with extremely low diff shares (usually only possible when setting diff manually) as the "weight" is calculated by difficulty / time .. not shares / time .. So if you only had a very, very low diff in a certain time you weren't calculated in until the diff / time was high enough (which then happened in a later round )...
I've lowered that limit so that now you should get paid for every round even if you have superlow diff / time ..
I really have no clue at all why you want to do so Any reason to share with us why you close the pool when dev around but re-open it when dev gone?
probably the gentlemen will pick up the PiCoin and start to develop it. If anyone wants to continue the developing, I will donate no less than 10k picoin.
