Very interesting. I would just add a couple of things which were taught me as a beginning knitter, by a Scottish woman who had been trained in school to knit in a style which was probably meant for cottage knitting. Her movements were much shorter than Stephanie Pearl-McPhee's, partially because she didn't take her hands off her needles (the right one of which was anchored under her right arm), and only flicked her yarn casting finger. Her knitting was so fast that it appeared to be a blur, even though her movements were so short. The other thing is that in order to knit to gauge, it's important that the new stitch is moved along off the tip of the right needle, because that way the needle size will determine the size of the stitch, which should wrap all the way around the needle without being sloppy or loose. It may have taken a little more effort to learn to knit this way initially, and I certainly wasn't the speediest knitter in the world at 8, but even then my knitting was incredibly even, and I didn't have difficulty knitting to gauge.
