I think the issue is that Suprnova uses a very short "N" value for PPLNS calculations on ZEC. This makes the results extremely variable. If the N value were increased, payouts would be much less variable, but it would take longer to get your coins.
Anyway, it's very possible for your shares to be worth nothing with PPLNS. It's also common for them to be worth 2 or 3x as much (or more). It all depends on luck.
I agree 100 percent.
Ocminer, you still have not replied to my 4 support requests of 2 weeks ago so please don't go around claiming that your available everywhere and if we're not able to reach you it's our problem.
Ocminer, pardon my arrogance but if I understand the mechanic correctly all you have to do to solve our issue is increase the N value to a few times the share number of an unlucky round.
Can't you do that?
