I posted a chart here a thread or two ago. Many people I've shown this to wanted another triangle and descriptions, so I've added those. I figured I'd update it here as well...
People are expected to not identify all the way in a triangle's corner in most cases. They could be close, but it's a fluid scale that's more descriptive than the corners could ever be on their own. (Or at least, that's the goal.) Ideally, everyone should have one dot on each triangle. If you're aware of a case for which that's impossible, I'd like to know of your example, as that may influence adjusting the chart.
Also, better terminology for my definitions or shorter ways to say precisely what I mean are certainly welcome. (As well as other bits of critique/advice/etc...)
