In suprnova last week I was doing 450 XVG per day per miner, when whattomine says around 430. I have changed for two days to DGB and now the difficulty of XVG is down to 400k. Yesterday I switched again to XVG_MYGR (suprnova) and I don't have 24h yet on that 400k difficulty. But the hour earnings says all the time between 50-55 per hour for two machines (so 25-27 per machine). You can do the rest of the calculations.
My "last day" is currently 525 XVG.
What port are you using , please share
stratum+tcp://xvg-mg.suprnova.cc:7722 this one is for me.
Now I checked my earnings again. 1191 and for 23 hours. Whattomine now says 1350, so I am little below. But I think the difficulty got dropped little since yesterday. I will follow closely and will let you know. But the difference for now is not big -100. After one hour I will have full 24 hours and will see.
