The most likely heel-and-toe downshift in AX is 3d to 2d, but the braking will be much harder than you should be doing on the street. A 3d gear straight is fast for AX and almost certainly will be followed by a relatively slow corner. Getting to where you can threshhold brake while heel-and-toeing will take a bit of practice.

You know, even after all the heel and to practice I did, there were only about 2-3 spots on the course I could actually do it. In the end I doubt I was even heel and toeing at all during runs cos I was spending so much time concentrating on the track. I'm hoping I can get to the point where h&t is natural, and I suspect, as you say, incorporating it into every single stop I make (on street) is the key. There's one corner on my route, offramp, into a 90 degree left (no stop sign) that requires pretty hard braking (speed limit plus alpha->20mph), that's the closest to autox on my "course". It's also the hardest corner for me because I haven't figured out the timing yet.

One question, is it better to downshift 4-3,3-2 as fast as possible just before the corner, or to go 4-3 continue braking then 3-2

as opposed to

BTW, I reset my mpg gauge before autox, at the end of the day my average was 9mpg
