I've recently switched to multi coin mining (which auto converts to LTC).

But does this look normal?

For the last hour+ my balance has not been increasing, and in that pool stats you can see even for blocks where I have shares, the payout is 0. Perhaps with only 2 gridseeds it is not feasible to be coin switching? Better stick to one coin (LTC)?
