No, I dont look at usd or btc as I understand that it is price sensitive. I look at coins I mine on the statistics line just before BTC/day. And I checked many times, monitoring for couple of hours, that statistics gives more than double as you really mine. If I would be able to get this amount which is showed then it would be about the same as to mine in other pools or even many cases better. But unfortunately its always very very over boosted. The coin should be for very long times over 200% to get better profits then elsewhere,which is very rare case.
