The next difficulty increases is now 30%+, if you compute based on your price, 30% diff increase and the end of August mining start, ROI by mining will never happen.

Looks like that is already built into the calculation of ROI in the form of a predicted daily difficulty increase.

If you mine last week of August, the Initial Coins per Day is around 39 not 65.90257387, so its a different result.

What calculation did you use to come up with 39?
