You're probaly right on LTC dragging down the profitability. It's doubled in diff since BCC went POS and now needs another 1Th pool speed to make it consistent.
I'll drop it for a few days and see how it does.
So that is the explanation why even mining the most profitable algos with MultiPoolMiner I get half or 1/3 the expected income over 24 hours?
I'm no expert but wouldn't make sense to adjust profitability by taking into account the time needed to find a block or simply multiply the profitability with poolhash/networkhash ratio?
