If I had to guess I'd say that ocminer fixed the hashrates in the pool (they are now showing sensible values instead of the crazy high ones before) but he's still calculating the expected earnings based on the previous ones. In any case, I doubt it matters much, I stopped mining in all but one RX480 card and I don't have high hopes for this coin. The dev is nowhere to be seen, there is no windows wallet, the price in cryptopia keeps dropping... not good. Anyway, I hope I'm wrong!
