Edit: Deleted. Been oversharing a bit re research I'm doing, and the payoff is replies from folks who haven't bothered to go and take a look themselves, which I then have to spend more cycles refuting, etc. So best to just go back to the first step and not overshare and recover the cycles I'd spend on the rest of it. Admittedly I'm tired and pissed off, but yeah. HN won't let me delete this so I guess it's just a deletion edit. Sorry.
