This pool has low payout and doesn't match whattomine. Even with lower network difficulty in the past 24 hours, their zclassic mining pool still averages less than ~36% of what is reported in whattomine.
I was supposed to get 0.455xx ZCL according to whattomine (2% miner + 5% pool fees already deducted) but only registered 0.2870 ZCL payout on their 24-hour average chart. I also have 2 pending blocks that have been that way for more than 12 hours.
