I think they should have a 3 part qualifying, and for each session you have to use different tyre compound. So could set 1st M, 2nd S and 3rd SS, but obviously first session your at risk of not making it through as others could be on a faster tyre than you, 10 knocked out each session. And make it, if you qualify in the top 10, the tyre you’ve qualified on is what you start on, and the other can chose what to start on.
Could really add a new dynamic as ideally you’d want to go for poll on the SS, but you’d had to do the other sessions on slower tyres and at risk at not making the top 10 at all (if other drivers use SS in second session) think it would really mix up the grid, because a top player could risk with meds first session and qualify 21st. And another way round, could go S first then SS and making it into the top 10, but then would have to so the last session on meds and start the race on meds! It would force people on more of a variety of strategies also. I’m my league I think about 18 races are 4 stop SS,S,S,S,S then rest of the way, then 3 or 4 races 3 stop S,S,S,M and Spain is 4 stop S,S,S,S,M and that’s it
you can make it much easier by qualifying with the amount of fuel on segment 1 (where, for example, 8 laps on M will be faster than 14 laps on C), this will clearly give an impetus to a variety of strategies,and the number of pit stops depends on the number of managers going to their number (if 4 managers go to 4 pit stops, then most likely this state will be lost, although there are always exceptions))
