i got even down to 50% of what was monitored on whattomine when i were mining ZCL. I dont say that you should pay me, but that was over 2 days of mining, then i went mining on other pool.Now mining ZEN on suprnova is more accurate but still few percent lower last 24 hours, but few days before it was accurate and even higher for some percent even up to 10 and maybe little more sometimes, so i cant complain at mining ZEN at suprnova.
