Mining with BFL at 440 GHS over 24 Hours and no bitcoin?
Consider consolidating to one pool.  Pools have a payout time "window" for example, shares per 24 hours. So, the more shares per 24 hour windows mean a bigger slice of the BTC block.

Three pools, no usernames?  How are your miners ID'd in the pools' systems?  Pools usually require an account/username to ID your miners' work for payouts, unless you're using P2Pool, then it's just your payout addy.


My first idea is, unless you're using one of the BIG FIVE pools, you only get a payout once a block is found in that pool.  BTCGuild, DiscusFish, Eligius, GHashIO, Slush...those see 5-20 blocks a day.  Other pools see much fewer, so don't expect any constant payout unless you're in one of the BIG FIVE.
My second idea is difficulty.  2.2+ billion difficulty is rough on a mining chap, and luck plays a big part when mining (many don't tell you that).
