Why aren't I making what coinwarz says I should be making?

[lionheart2243]

Hey guys,
I mine in the hashcows pool, which mines the most profitable scrypt altcoin and converts it to BTC. However, using the coinwarz calculator at 650 kh/s (I mine with a 7950) the most profitable coins should be earning anywhere from $7-$10 a day. After 3-4 days of mining, I'm averaging roughly .0035 which is around $3 a day.

Why am I making so much less a day than what coinwarz says I should be making? Is hashcows a slow pool? What am I missing here and what can I do to see these supposed potential profits?

It could be related to the difficulty increasing over the span of a few days as well as your stale rate you can use http://hash-to-coins.com/ as well to get an estimate.

You also may want to trade manually and output all your coins to Cryptsy. You earn points that can be traded over to BTC as well.

Well shit...
Though I'm still skeptical, I had only made .0105 the past 3 days, but today I made .1350 in around 18 hours from an apparent surge in MEOW. I've heard from a fellow 7950er that I should be making $5/day easy, and today's earnings puts at about that. Maybe my sample's been too small, but only time will tell. Still though, coinwarz claims the best coins should be going for $9ish a day...

I guess its possible your pool was consistently unlucky (take abnormally long to solve a block, etc), but I imagine that might affect your type of pool less? Anyway, that's just something that can happen. A pool can be abnormally lucky or unlucky in terms of how quickly the pool solves blocks or gets orphans, which depending on the payout type would affect how much your card mined per day.

Difficulty varies from day to day
