3/4. hug curbing maybe 2 feet off remaining in 4th gear all the way through these and then all the way through esses

5. setting up entry with straight line coming out of right hand ess, then downshift to 3rd under braking and accelerate rolling out to straddle curbing

en route... shift from 3 to 4, then 4 to 5 (for me this is a must about 1/2 way to turn 6)

6. light braking with downshift to 4th... would be better with srm or perfect heel-toe, as right braking zone appears to be after initiating turn

7. make a straight line on bank of turn 6 towards 7 turn in point, brake hard, down shift to 3rd while braking hard, hard turn into to apex (I over turn steering input to get the understeer started) then let the front wheels catch into straight line and get on it as car settles just before apex

long straight, i end up in 6th gear just before downhill if I came out of turn 7 as planned

10a. downshift to 3rd in the heavy braking zone, hard left turn with slightly late turn in to get somewhat on the left side of 10b turn in and get max speed coming out of 10b

10b... exiting 10b, shift into 4th hopefully before crest of hill... when I time this poorly I was hitting a divot on top of hill (driver under red mark in sign) and getting a little squirrely... usually shifting 20 feet before crest

11/12. straighten out at bottom of hill and shift to 5th before start/finish, hopefully not unsettling the car! I'm being a big puss in turn 12 and holding 3/4 throttle so my eventual shift point is probably sooner

Must be the different levels of power that put you in the higher revs quicker being your FI. So I'm speaking from a NA mind set. T5 I always down shifted to 3rd also (I think Mike doesn't, sometimes) to pull you up and over the crest faster (especially to pass) and then shift to 4th. But never got to the point of shifting to 5th (again NA mind set), never got that high in the revs.

Back straight before T10a. Again must be the power difference, I top out 5th well before the dog leg there but never could reach 6th gear. I brake late on the descend before T10a hitting nearly 140-145mph. I'll continue later. Have to go to work.

After 10b I used to short shift to 4th before the bridge/ crest. Not sure about a dip. But now I shift after the bridge as I'm starting down the roll out far left. I felt I was losing way to much momentum by short shifting.

And as far as T12 and 3/4 throttle. Me to. Me to. Butt loads of momentum in that descend. Always treat with Hugh amount of respect. I've heard the big dogs talk about going full throttle threw there and it will hold if entering a late apex. But I'll save that for for later years.
