I had the same doubt, so I wrote a small Java program that calculates the "effective" GH/s for the S1 based on this formula based on the values reported by the S1:
EffGHs = (DiffA + DiffR) / (DiffA + DiffR + HWE) * GHs
Where:
- EffGHs = Effective GH/s
- DiffA = DiffA reported by the S1
- DiffR = DiffR reported by the S1
- HWE = HW reported by the S1
- GHs = GH/S(avg)reported by the S1
I let the miner run for about a week with each setting and then calculate this value. So far by best value is 193.8396 GH/s for a frequency of 381.25 (5e05 freq value) and a timeout of 37.

Thanks for the formula! I've got a spreadsheet going to calculate this. Next step will be writing a program to automatically pull this from the cgminer API on the miner.
