Thank you

Great lesson, this is one nice explanation on this topic, and your playing makes the point even better than the words do.

And yes! Changing keys really affects how our brain perceives fingerings, just because the dot placement on the neck changes. I've been trying to reduce the number of possible fingerings, so it becomes more about the ear than the thought process. For the 3-octave arpeggio, what works best for me is taking one fingering, e.g. frets 2–3 on the 6th string and 2–5 on the 5th string, and moving that same "cell" up in octaves.

You could have different cells for different inversions, but that way we're basically doing what pianists do: same shape, every octave. And it's way simpler.

Thanks for putting this out!
