This pool seems to have been messing around this morning- of 3 machines mining the shares are only showing for 1 of them on the website
http://dtc.gpool.net/user/[payout address] and payout was thus correspondingly low. The other 2 are running multi core jobs so am wondering if this might be the issue. Either that or the pool have decided to charge 68% fees ;-)
I dont really know. I am mining in the other pool currently to divert the power to the small one. It isnt good for only 1 pool to have most of the mining power.
What i have noticed though is that sometimes you are getting very slow income while others time i get like 100 times more income. This though happens for a few minutes up to an hour max. i suppose pool pays back what owns or something...dunno.
