I got a refund I was very satisfied with, but you can't base it on the stats on the pool page because those were way off. I was in the top of miners on the pool all the way from the start, and I got maybe 10% of what the stats page told me per 24 hours. As others have said, mining at low difficulty will only net you a fraction of what you "should" get.
problem not in what show in statistics.. problem was in incorrect calculated payouts. and about recalculate payouts, owners of the pool only says and nothing want to do ... in my acc i do not see any changes .. wrong payouts not was recalculated...
