I'm by no means any good at this game, I play with a few assists on and 95 Difficulty.
I have just noticed in a race on Australia that the Ai drains less ERS and also recovers more of it going into a corner, I was in a Red Bull and behind me was Leclerc in a Ferrari.
We both were on ERS Mode 4, as a starting point I took the white line right before the final corner and the finish line as the end.
At the start I had 70% ERS and Leclerc 12%, at the finish line I only had 58% (-12%) and Leclerc 5% (-7%), I was also recovering less when braking into the same corner +5 compared to him +8.
I know recovering ERS under braking might be because I use a few assists but the ERS drainage on the straight can't be because of it? Is this because of the difference in cars, assists or just something that needs to be fixed?
If it is an issue I don't know if it has been addressed already but I would like to hear other people opinions on this.
