I am just wandering if you staff (except driver) for example Chief Designer improve your team if you get a better one. For example of you get a better Chief Designer does design improve for your car?
I could be wrong but I believe the staff graph works like decimals. EG a level 9 staff member with a maximum graph might be 9.9 where as a level 10 staff member with almost no graph is 10.01 or something, if that makes sense.
I saw a big difference in chassis developing, using level 3 and level 6 chief designers. The chassis is evolving more quickly in terms of % and ofcourse the car is quicker than it used to be with designs from level 3 designer. As for the technical department it affects for sure the time you do the pitstops, i m not sure what else it affects.
