AI Straight Line Speed

I felt that Problem in Shanghai Sprint now i had 1,5 seconds Gap and used some Ers with a 35/31 Wing setup and lower Suspension setup. But the long Corner before the back straight they gain 0,1 and then at the end of the Corner they gained only with this Straight to 6-9 if i dont use my FULL ERS deployment in my Team (weakest Performance Ferrari engine) and when they were 0,9 behind me they just blast past me no matter how much topspeed i had they didnt even need drs. This needs some adjustment only for the AI theyre also always round about 50-80% in every lap how do they recover always much and still gets charged so fast? Its a Joke how youre always Winning everywhere and then theres a straight where they can win back all that lost time. Also after a Red Flag the ERS wasnt fully charged for some reason it was for me on 40% only. Maybe look and change these things. The AI must be full priority to get them as near to a Player as possible of course they should be a little better but not over exxagerrating with the Performance.
