I'm on a different boat... I know exactly how to do it, just having a really hard time executing it... my finger dexterity and being able to focus for that long are the main culprits. I managed to apply what I knew had to be done and lower my time substantially, but doing it more acutely and consistently is becoming a problem I'll probably not be able to overcome... but I'll try!
I'm not kidding with the way I control my fingers/hands... I mean, I have trouble writing an SMS on a phone! Let alone throwing the NSX around Nur! hehehehehe I think I'm not very well "wired" for this thing with sticks and buttons and all that
One of my main problems (besides not being consistent) was that I didn't run the apex of turns like I should (and like I do in real life), so I was always, and still am, going around the apex... for some reason, when I'm looking at the screen, I'm having an incredible hard time measuring distances and figuring out the car physical proportions in relation to the road... I've been correcting that, it's a mental game, I just have to say to myself "turn in early" and "turn the wheel more" on almost every turn, and that worked very well, but I still miss the optimal lines a lot.... it's my brain tricking me to go wider, I don't know why...
Another big issue, is brake sensitivity... I'm braking too hard, it took me months (years?) to finally be able to modulate the accelerator, now I can do it more or less effectively, but the brakes... oh my... I'm a mess!
Then there's the consistency and focus problem, it's almost a miracle for me to run the entire lap without crashing or going off-road a couple of times, that obviously will keep me above 8 min
Well... it's not easy. But it's very rewarding, and fun! It's great to be the last on the leader board, I have so much room for improvement! ahahahaha
