I just noticed - I think there's something wrong with your chart. 17 bitcoiners per 10 megahookers? That's nearly six hundred thousand hookers per bitcoiner. I'm not sure that's possible, even with the legendary feats of endurance one develops by becoming a bitcoiner. Perhaps you've estimated the curve incorrectly?
Sorry, maybe I should have made the chart clearer.
A mega hooker a a measurement of difficulty and not the number of hookers. An average hooker rates at a difficulty of around 10 mega hookers or 10MHks. But remember not all hookers rate the same difficulty. Your average bitconer, for example, is likely to seek out hookers of low difficulty due to the non-native environment.
I hope this clears things up.
