This just isn't true. anyone else have this experience? On my own miners its a close approximation of my hashpower. whatever the estimates.. your accepted submits are your accepted submits. Estimates aren't always accurate but they are close.People's misunderstandings of pplns and of waiting for blocks to confirm for payout always get complaints.
Besides, anyone who feels they are not getting what they should be.. I always will review and if need be, pay out extra out of my pocket to satisfy them if they have a good argument.. support! sometimes things do go wrong here and there.
I've mined on "http://dgc.scryptmining.com/" until went down with 2700 kH/s ... i have 5 7950 that all go between 500 - 500 kH ... why do you thing you pool goes so slow and nobody goes there .... recheck your settings ... i know 100% this is true
