I think race feel ai is better because they are better at conserving tires or their tired get less ruined
tyre make a huge difference this year and if you have a 100% race I notice when my tires are over 30% I start losing more than ai is losing
so unless I do 4 stops I struggle to keep peace with ai and in my team with novice team my pit stop always sux and get trouble so I lose even more
I can always with worst car get qualification 7-8 place @ difficult 79 in all track I learned to be very consistent in the 16 track I selected I never need to change difficulty
but my result in race race always between 9-12 (9 in the track I know better and 12 in the track I still end up doing some mistake over 60-70 laps small mistake but still enough to lose 1-2 position)
I do agree race is slightly stronger than qualif not by much but mostly I think because tired and the fact that ai is extremely consistent they rarely make mistake I do make mistake in some track over 60-70 laps
