The aero coefficients vs lap speed charts for the next two rounds are below (I have kept the convention of Cl being positive for downforce, so if you are using the other convention (positive for lift) remember to swap the sign!
I've extended the range to encompass the sort of results you were all getting in the last round. You can see that both of the above tracks reward a much lower drag set-up than Monaco.
Balance vs lap time is shown below (in this case for magny cours for a cars have Cd.A = 1.6 and Cl.A = 2.8, but the trend will be similar for other tracks):-
Another request (sorry Machin I don't want you to waste too much time): I would be glad to know the total energy "consumed" by each car (in the hypotesis to spend all accumulated electric energy in the same time lap).
I'm afraid I would have to re-write the program to obtain this energy data. From a design point of view it wouldn't help you design your car; you should be aiming to increase your downforce, decrease your drag, and get your COP as close to 1.83m as possible.
If it were me doing the challenge my approach would be to design three basic cars; low downforce, medium downforce, and high downforce. I would then run some CFD to obtain basic aero cofficients for the three arrangements. I would then plot the three cars on the lap speed chart for the up-coming race, as I have done below:-
In this example I find that my medium downforce set-up is the fastest. So I would use this set up as the basis for the Magny Cours race, and I would try and work to make small changes to improve the efficiency of that design....
