I really don't know. I just let mine run and only look for payouts after a few days, sometimes a week or so.
0.1 ZEC is worth about $23.50 at the moment. Is it really worth trying to get payouts on less?
That is a good strategy. When you start on a coin, always mine for a week. You will see better results, compared to constantly jumping and trying to jsut mine the minimum from the coin for a payout and then moving to the next thing.
