Am I reading this right?

The difficulty growth rate over the last 3 months has been about 100%/month.

So even if I get a 60 GH/s BFL miner (EDIT: at $1299, before the price increase), and start mining on October 1, with free electricity (which I don't have), assuming the 100% growth rate per month continues for the next year, then at the current exchange rate, it only just barely breaks even? A.K.A. Zero ROI.
