Where is the box to input network difficulty?!? Without entering that, or it pulling it, I don't see how it could work.

--edit -- Nevermind I see it does ask for time between blocks, so that should be enough to calculate.

If you look at homepage of any of the sexy pools, they tell you how many coins per day that pool gets. Just divide that by the hashrate of the pool in MH. Then you get coin per MH, per day.

Just times that then by your hashrate...

As of right this second (will change)

4420.369538 coins per day
1.32TH is same as 1,320,000MH

4420.369538 / 1,320,000 = 0.0033487648015152 coins per MH per day

So for 230MHs rig = 0.7702159043484848

Which on Thur last week it was 1.2

All due to the network difficulty rising...
