practice programs broken

This is happening to be as well on Xbox series S. I change the difficulty every weekend to balance what I did in the race before, simply because I can't actually find a correct difficulty to stick to, like I'd prefer. Currently I'm on 60, at Monaco, but don't get held up on that--this happens regardless of difficulty. I did a 1:11.797 in my qualifying pace practice program, 2.5 seconds faster than anyone in the field for practice 2, and failed. I can't even duplicate that run, it was as close to perfect as I'm capable with my skill. Popular difficulty calculators day I should be running at difficulty 84 with that kinda run. I have no problem underperforming in the race or even qualifying assuming I feel like I'm in the right difficulty level, but it's super costly to fail practice programs, and you only get so many tires to keep trying with. The programs (race strategy, quali, tire wear, fuel, all of them) dictate an unrealistic pace for the difficulty level assigned to it. If I do a 1:11.797 in actual quali, I'll be first by miles. So what gives?
