Update:
My basic analysis based on what I see in the graphs along the length of the run
1. * General comment : Frankie's tires are no less grippier than mine. Peak G's barely vary and at times his are greater than mine.
2. My launch is substantially better, I get the car hooked up at a higher RPM (not shown in this graph, 5500rpm vs Frankies 4000) and carry that speed all the way to the first braking point.
3. We brake almost same amount, except that he peaks and feathers off, while I roll on to the brake, however our time spent braking is identical! And because of this I carry more speed through the initial corner. More on this later.
4. The next part is interesting, even though I am part throttle because I carried more speed I feather myway through the next section at an overall higher speed before coming to the braking point for the tight S
5. again we brake for an almost identical amount of time, with Frankie peaking harder and feather off while I feather the brakes into the turn. We decelerate at an even pace but I carry a bit more speed through it AND, if you look at the initial map, my line is simply tighter.
perhaps this can be attributed to a gentler brake deeper into the corner (so more front tire grip) and more confidence in the car completing the turn
6. Next part is interesting, Frankie goes WOT but he's still in 2nd gear while I shifted into 1st during my braking for the S. So even though I am feathering the throttle I am putting down more power, until I go WOT and accelerate much harder before we start turning right.
7. during this turn our stats are very similar, with the exception of a higher peak speed while Frankie has higher peak Gs, if you look on the GPS map you can tell he took a much more even circle while I did an egg shape hoping for a straighter line into the two-cone box
8. Going through the two-cone box we're doing pretty much the same thing. Not sure for Frankie but the reason there is brake pressure there is because the VCS, even though its turned off, still turns on to help the torsen do its thing... the two-cone box was pretty grainy so maybe that's why
9. in the long sweeper we see that Frankie ultimately attacks it harder and WOT 100% through it and is rewarded by a higher entry speed. I was much more conservative but at the crucial point I keep my foot partially on the gas which had me end up carrying more speed overall through the entire turn.
10. as you can see, the fact that Frankie let off completely resulted in him engine braking much sooner than me, this is reflected in both the G-load and Speed graphs.
11. I bleed off the extra speed by braking harder during the little straight before the hairpin, Frankie, in retrospect, having bled off all that speed, could have probably not bothered to brake at all until right before the hair pint
12. the hairpin is we start to diverge completely. As you can see, I braked harder and shorter to settle the car and my steering input was SMOOTHER yet QUICKER
13. as per the GPS map, this results in Frankie taking a much longer way around the hairpin pylon, and the end result is Frankie simply having to take a longer route through the slalom, hitting his turns at a much different rythem, turning before the pylon where as I was turning at the pylon
14. as I mentioned before, GRIP isn't a problem, we're hitting the same G-Loads, however as I am more consistent in this section with my throttle, I have much less speed variance going through it
15. the "BOX", Frankie goes nuts here and his throttle is ON/OFF/ON/OFF, while I maintain a near uniform steering and throttle input
16. the entrance to the exit is executed better by Frankie. I decided to take a tighter line but felt no grip in my tires, partly because I've had it setup to almost eliminate oversteer so I just casually turned and semi-coasted past the beam while Frankie rocketed into it like the boss that he is.
in the end, however, I was 1.9 seconds faster.
So two main things to draw from this
I still have room to be more aggressive and Frankie has a bit more training to do with his right foot.
But I think ultimately what won this for me was A. Better launch B. Overall smoothness with part-throttle to limit speed loss. C. nailing the hairpin entry, transition and exit.
