I know this is very specific track that's not to everyone's liking. I myself have troubled history with it (despite liking it a lot), never being able to gold it in GT7 (and a shameful bronze with the NSX where I just surrendered). But...
I know you're capable of reaching the gold time on it, Jerome. Your recent form and results are proofs of it.
The easiness of invalidating laptime might be a bit discouraging, but I believe that continuous series of laps is the way to go. When invalidated, just use the rest of the lap to test your lines of other corners and put it to use on the next lap.
I did stints of around 9-10 laps that last over an hour - it's long enough to find your rhythm and not too long to feel tired or drained. On those stints only like 2 laps were valid, but those were the laps where I improved. Here's how it looked like for me:

I know your work schedule is not on your side now, but it's so close. I know you can do it!
I've shared my replay with tags of #gtptt #tmtk #titans if you want to look at it, maybe you'll see something useful. That's a pointer for
@MUC76, too.
cheers,
Leszek.
