GN+
I'm having trouble...i'm running what seem to be flawless laps..going from rumble strip to rumble strip and having no off-tracks or anything...and I can't even match GT300 times from the other events...and i've been playing Gran Turismo for years with successful outcomes...I don't know what i'm missing here...
As eatsviper4lunch stated, it takes a bit of time to put down a stellar qualy lap. I usually do one 40+ lap session, or a couple of 20-30 lap sessions if I have time.
For example, I ran my first Grand Valley session last night, about 30 laps. The first 5-10 laps are "sighting laps", where I basically try to get a feel for how this car handles around this track, what speeds can be held through what turns, how it handles certain braking zones (turn 8 for example). My laptimes are dropping bit by bit, and in the case of last night I put in my fastest lap on lap 18 or so. The remaining 12 laps were spent trying to better it, seeing where I can go faster, but in this case not being able to hook it all together for a single hot lap (I know I can go faster than yesterday's fastest lap, but I couldn't do it last night).
Anyway, my point is that it takes time and practice, and you'll become more comfortable with your car as the season progresses. And if nothing else, you'll become a better overall GT driver just by competing here, even if you don't place very well.
Give it a go, see how you feel after a couple of solid rounds 👍
