Glad you enjoyed! (And sorry for not responding sooner; I wish there were a setting that informed me when someone replies to a top-level post of mine!)
Don’t take the tests too seriously. Supposedly the RHETI somewhere in the ballpark of 80% accurate (although I’m not sure how they determined that), but in my experience it’s just not nearly as helpful as talking to someone who can actually use the toolset. Threes, Sixes, and Nines in particular seem to have a lot of trouble with tests: Threes keep wanting to be whatever the “best” type is, Sixes keep double-guessing their answers, and Nines tend to see most of the choices in the forced-choice tests as relatively arbitrary (“Well, I’m like A when I’m with these friends but I’m like B when I’m with those friends, so I could go either way”).
I think training System One, like I described in the presentation, is much more likely to type you and your wife correctly. Although as you said, I’m pretty sure you’re a Nine.
I hope we can expect you at the next meetup!
