2) You have the Initial Mining Date as September '13. You change that to October '13 (cuz Sept is basically over), and all the numbers go red. As in no profit. Am I looking at this wrong?
When you set the date to October, TGB shows an initial difficulty of over
298 million which is completely wrong. Our miners start shipping 3 days from now when the difficulty will still be
149 million. This is a big flaw of TGB due to its coarse 1-month granularity. I explained it here
https://bitcointalk.org/index.php?topic=303376.msg3249572#msg3249572Another dramatic way of observing the flaw is this: TGB with October as initial date will suddenly start showing profits if you use the calculator on October 1st (because the initial mining date will fall in a month the same as the current day).
