Maybe there's another thread somewhere for this but has anyone discussed that even with so much power of our Antminer S1, it's looking very doubtful that we're gonna get our ROI of 3.15BTC? [I'm not complaining at all; as I suspected it from the start before I bought it

I just want to focus the discussion on ROI wrt Antminer S1. What are your plans/contingencies?
I'm basing my numbers from playing around with the S1 since last night (about 13 hours worth of data); so not really significant sample size.
Many thanks to sushi and Bitmain for such a FAST shipping and so easy setup (literally 5 minutes; of course I was timid and took my time so maybe 15 minutes setup). I had everything ready; table, power supply, dd-wrt router brdiged via wifi to my main router (same one I'm using for my "downed" Litecoin miner).
