Same here, when I was trying to track it, the autoswitch returned less. ALot also had to deal with market prices of the alts as well.... it just wasn't as effective as I'd hoped. So i just stuck to 1 currency.
Anyone have a few Z9/minis so they could run MPH-autoswitch vs. something like Prohashing for 48h, at the same time? I've tried to alternate pools... but small differences in pricing on different days always throw things off: it would be best to have 2+ Z9's in parallel to get comparable numbers.
