Up shifting while turning and accelerating can aid rotation...so maybe do it on exit not entrance and on the brakes

I think a PDK would wonder how the heck it ended up in an NA Miata! Good idea though for those with cars with both transmissions.

So here's a fun one, I guess.
I played around with going to second gear at turn 5 at Summit Main. It works pretty well.
But then I'm in a weird spot at turn 6; I can either stay in 2nd but then I have to go to 3rd while I'm in turns 6 & 7 with the car pretty fully loaded, which seems wrong and tricky and generally uncomfortable. The alternative is to UPshift while I'm braking, which seems like an insanely counterintuitive thing to do. I could upshift slightly earlier than while I'm braking but if I'm going to go through the trouble of getting down to second at 5 it seems like I should use it for as long as it's sensible to do so.
Which of these two evils is better?
Start at :50 or so for the entry to 5 (which wasn't always this rough, I did this better other times). https://youtu.be/hvomj7Vml1Y?t=50s

I can't tell from the video but for a Miata you are probably at full throttle out of 6 correct? If that's the case you'll want max power so you'll ideally want to delay your shift until redline between 6-7 (I think that is a redline shift car). I say ideally so it might not be faster for you right now if you find that shift difficult and it messes up your control, but it's probably worth working on as it's the correct way to do it and will eventually be faster.

Do you mean that people tend to run wide at exit or the corner tends to shift balance toward understeer?

This sequence at Summit is quite tricky and is different one from car to the next. In a fast car 6-7 is a double apex and then 7-8 is a chicane. In that case I would say you could up shift early as you don't need all your power in 6-7. In slower cars you have 6 as the double apex and then 6-8 is the chicane and 7 is not a corner. Then even slower cars there is no chicane and 8 and 9 are both full throttle corners and you are flat from 6 all the way to 10.

I think this is just one of those driver improvement spots; when I stayed in 2nd through 6 the extra powah was noticeable and in a vacuum is certainly superior. My issue is that the car is pretty close to maxed out laterally and I'm not super comfortable holding the car one handed while shifting in that condition. Adding to that is the fact that I'm pretty dedicated to keeping my hands in the 9/10 & 2/3 area of the wheel at all times, so I end up with my left hand at the top of the wheel and moving my right hand from the bottom of the wheel to the gearshift to do the shift is physically awkward, especially if, as I suspect, that shift needs to be done pretty quickly to make being in 2nd there worthwhile.
The default 7/10ths approach to this whole segment is to shift to third in 5 and just stay there. It's clearly slower but much simpler.

Yeah. I'm flat from 6 to 10 in my car.

Here's a great YouTube video site for driving instruction. I'm not connected to them in any way; just think this is a great resource for both inexperienced and experienced drivers.

It is so much about the release. 50% to slow you down and 75% ( or more ) balance.
As Jackie Stewart said " I didn't start wining races until I learned how to get off the brakes."

Sorry, didn't see all the replies to my comment about Turn 3 at Laguna Seca.
I have never had a chance to walk the track. Unfortunately I don't live up in the area, and I only drive there once or twice a year.
So do you lose the camber at the exit? Or is it more a problem that is driver induced? Is the track equal width prior to going into the corner and on the exit? It seems like when looking at Google Earth that it is a little narrower.

I have several excellent executions demonstrated in the data of Turn 3 done extremely well. When compared to folks having difficulty, it is primarily driver induced...
