I assume S397 and BMW have given concrete goals and aims for the organisation of this series?
Please confirm that the written objective is only to have 10 finalist names, then we can't argue any more with you personally.
If that is not the case, then the stubborn attitude of "we won't do the job better because I say so" is one of the core reasons for rF2 falling behind competitors like iR or RR in the esports/competition side and seeing tens of times less interaction from fans and other participants.
No "new competition system" will help unless this fundamental approach is changed. You just can't say that providing participants more info won't change anything. It's the simplest things that would make a big difference,create the appeal, invite more drivers and also existing drivers to take the obligation more seriously.
The professional simracers participating thanks to the prizes are the main thing vindicating this championship. The top drivers who you intend to forbid entering (?) are doing the majority of advertising for rF2 via livestreams and other social media, engaging people who end up paying for and playing the sim.
Nothing against the physical sim constraints or your time restrictions, those are understandable, but all we expect is to hear something like "Thank you for the suggestions, we will try to do a better job because our intention is to do things as good as possible and provide the best racing enviroment"
