I need advice about pool, at the moment we are mining on coinmine.pl, all online calculators are saying that I should get 6.6 zec a day, but I got only half of it, I'm aware that this is the mater of many factors, but I know that something is wrong, your advice would be much appreciated
dwarfpool.............read my earlier post about it 
Coinmine I've been aware for awhile. That's why I switched to flypool only to find the same anf very unstable. As with coinmine flypool also reports 10% under. Testing dwarfpool now and so far do good.
