@njed "The big question is can we slow it down? How do we judge that?" I tried "judging" the progress once! I designated a space in my home (long hall) and timed how quickly I could get from one end to the other three times. I figured between the slight jog and the turning process, I'd lightly covered most of what I needed to know. I wrote those results down and thought I would try again in a given period of time, say 3-4 months, maybe more.
Sounded like a good idea, but I never followed up. That was a couple of years ago. I wonder if I could even find that information I recorded. If I do, I'll try it again and let you know!
