According to the spreadsheet, we currently have 18.5 TH/s of hardware "arrived", but looking at eligius, it looks like a lot of it isn't working reliably yet.

I think the goal this week has to be to get those things having reasonable uptime, whatever it takes, or to hold CT responsible for delivering working units.

Current diff is 3.815bil.  18.5 TH/s should make:

1.0/(3.815*1000*1000*1000*(2**32)/(18.5*1000*1000*1000*1000)/(60*60*24))*(25) => 2.439 BTC/day => 17.1BTC/week * 50% => 0.000628 BTC div

Our actual div was only 0.000087, about 14% of expectations.  Presumably due to hardware unreliability.

Depending on how fast we receive hardware, we should expect next weeks' div to be OVER 0.0006 and if we receive all of our hardware, it could be as high as:

1.0/(3.815*1000*1000*1000*(2**32)/(31.5*1000*1000*1000*1000)/(60*60*24))*(25)*7*0.5/13595 => 0.00107 BTC/share


TL;DR: projections for next week's divs are 0.0006 to 0.0012 depending on luck, hardware arrival, and hardware reliability.  If hardware continues to be this unreliable, however, we could see divs under 0.0006 and it'd be *very* bad for us.

EDIT: I misread the div by a factor of ten *facepalm* *fixed*
