Absolutely classic hoaxie behavior, though, and give the lie to any claims he had of intellectual honesty. After being shown and, after much back and forth, tacitly agreeing that his "2.4" figure was WRONG, when he rolled out his well-practiced argument at a new board he went right back to the original.
Basically, he lied to them. As I said earlier; the only thing most of the hoaxies get out of discussion is a chance to rehearse. And sometimes, at least in the braver ones, they learn a few new buzz words they can show off to look (for a few minutes) like they know what they are doing.
