Updated the sheet 
https://docs.google.com/spreadsheet/ccc?key=0Ah7ZJVoobFY7dDRGQk1kdmJmaUJwZENKZUdNejJlWEE&usp=sharing#gid=0
- Changed the BTC sum from x14 days to 12days. In reality its closer to 10days. ( this make the sheet look better than whats going to happen)
- Increased 4.5GH to 5.0GH due to FW fix
* left the deltas at 'last delta + 5mill' - This is optimistic, I am hopeful the increase will slowdown.
Cliff notes:
- 1 board will hit hardware/power break point (40watt/$100BTC-.15kWh) in ~Jan 2014, making a sum of .348BTC(not including power costs)
- 1 board at (40watt/$200BTC-.15kWh) in April 2014 will make you $.04 a day after power coasts. ( or a total from now until April of 0.42108BTC not including power)
* if you are currently mining you would make 0.0768BTC this round ( this is > 20% of the total potential income from the boards). So IMO start mining ASAP
