You know perfectly well that one does not get to preach about a single right prediction. He had the opportunity to make more than that prediction, and he failed to take it.

Mm. I think there's wisdom in the approach of only making public predictions when you're very confident in them, and that may have been the only thing 75th was that confident in. (This isn't a very good approach for calibrating your brain's sense of uncertainty, but it has other benefits.)
