Hey, I have had a G29 since July with softer spring brake mod. Looking at your calibration the main thing that screams out at me is the brake saturation is maybe way too high. With it that high your brakes are like an on/off switch so it may be difficult to trailbrake consistently and smoothly, therefore raising tire temperatures and causing slow laps.
The original brake pedal on the G29 is too stiff so it's a requirement to turn up saturation but the mods should allow you to lower it quite a lot. I went from 50 to now 8 but I've also built up strength in my leg. I'm pretty consistent (at least for me) when I drive in my team.
In terms of the wheel settings, I don't know really. I play F1 2021 but I did play F1 22 when the free weekend was on. I found that the feedback was generally lacking and weak. I used the same settings I used in F1 2021. Just to add, I play the PS4 F1 2021 version on my PS5 as there is a clear difference in feedback strength in the two versions with PS5 version being very weak. Even when the strength FB strength is ramped up, it never achieves the same level. I think the problem still remains on F1 22.
I use FFB strength at 80, and the rest of the FFB options at 25 and wheel damper at 5. It was at 75 which meant a heavy, smooth wheel but then I realised I could never catch the spins because I could never feel the back go loose and the wheel was too heavy. At 5 I've never had more fun pushing the car and catching spins and oversteer, plus it comes in handy in the wet as you feel the fronts go far more (coupled with oversteer enhance on). Wheel rotation is set to 320.
