Actually I'm deadly serious about those tests. I have suggested them for 2 years now, at least unofficially. It is for 1 very simple reason, I'm not speaking about someone particular now but majority of FSR drivers don't know rules - fact. How many times someone sent wrong files or sent no files, how many times someone had wrong settings in game or in files, how many times people ask on server the most trivial stuff right before the race or quali, how many times people fail on the most basic of things, asking incredibly weak-minded stuff on the forums. I am not trying to offend anyone and again I am not speaking about anyone in particular, but the fact is that cpu power of certain individuals is lacking.
Now it is questionable whether it is due to lack of care, lack of intellect or lack of reading skills. That is what those tests would uncover and FSR could take certain steps towards educating their members.
Naturally such strategies would only cost FSR drivers, which I'm fully aware of which is why I never suggested it officially.
Now finally about your engine braking, you and almost everyone else on mod testing forum did literally nothing. Now 4 days before the mod is official it is a bit too late for making such changes isn't it. Furthermore it is not a mod issue, it is your setup issue or driving issue, but as far as I understand in your case it is easier to get the mod fixed rather than fixing the setup so that's that. Peace.
Edit: To reading comprehension I would also add communication and communicating your points across. Indeed a very useful skill to possess
