@Gomario JSP thank you good friend; I had a stroke of luck making it into the 1:54s and I'm thinking I should buy a lottery ticket after that.
The final S-curve complex is where I either win or lose this lap. The corner(s) I'm referring to are the sharp left then right under the short tunnel, T6 I believe. Much time can be gained here. I brake a little before the 100m board, try to slow to around 136 mph, then coast into the corner getting as far left to wall as possible, keeping min speed above 125 mph… preparing to throw the car right when going under the bridge, coming around and not exiting into the wall on the left side 😅 it’s a punishing series.
The devil is in all the small adjustments that get made trying to compensate, split-second, for how I’m braking before the turn, did I turn early or late, do I coast more or less, am I getting any desirable oversteer snap to the right, am I close enough to the wall to make a good exit… my brain hurts just thinking about it 😂 But actually dissecting the turn in this way helped me understand my reactions, why I react the way I do, making small adjustments, and then just trying again.
I saw an improvement when I committed to minimum speed of 125 mph in that series of turns. Whether or not I actually hit that minimum speed, it seems to force me to get as close to the left-hand wall as possible and set-up properly for the exit; the speed helps throw the car in and keep momentum moving forward and not into the left-hand wall 😅 Very, very easy for me to over-brake, causing the car to scrub left and hit the wall on exit.
For all of this strategy, the looong run-up to T1 is wearing me out

Happy with the results so far though I still, still think I can eek out a tenth or so, if the GT7 gods smile upon me
