My apologies, I think that phrasing was difficult to parse: the 12 month estimate was excessively pessimistic (i.e. it probably won't take that long, because the market is better than I expected it to be).
I had been basing my projections off of running a medium-volume low-touch business with average yearly account values in the $500 range. It turns out there is an addressable market for which average yearly account values are in the five figure range. More detail on that in a blog post Friday-ish.
