i experienced some differences, but started season (no my team) with ferrari and my character before patch 1.06
used to play previous games at 90 max......(no, i'm not the guy who says i play at 110 using only my toes and drinking coffee...... 😬)
and this year after some tests in quick gp mode, i set 65 for quali and 70 for race...
bahrein 1,29,7 (ai at 65); me 1,30,0
australia 1,20,1 (ai at 65); me 1,18,7
imola 1,17,2 (ai at 60); me 1,18,0 after patch 1.06
miami 1,30,2 (ai at 60); me 1,29,6 after patch 1.07
what i notice obviously is that ai is so much op and hard....and that it seems that quali is faster than race, with a quite constant ratio, between 65 and 70
but in miami yesterday, the race was full wet, set in 65...i started 1' and had so great battles with Lec, until he passed me and suddenly was at -12'' after 5/7 laps......so unrealistic.
regarding your time evaluations, i find it completely different but can be because you recorded them after patch 1.07 for australia and bahrein also if seems quite difficult to understand.
the final point: the real times are always beaten from ai too easily and at ridicolous difficulties.....they should match them only at 100.
