@TomasSlb24 yep, it's definitely not perfect and won't be probably in few years.. I wish there were more depth there and strategy choices, but it's what it is now. Like I wrote, I have feeling temps are simplified for AI in the code, hardcoded to increase in certain amount of time to the optimal and then kept there artifically. I could be wrong, but it definitely seems like it now (I really doubt it's a bug)
I'm pretty sure they were aware of the second set of hards/mediums issue before release, but didn't have time to implement it correctly and are now trying to get away with that for F1 22. It wouldn't help much with 50% or less races, because not that often that you can make 2 stops work in any case (if they would give option to increase the speed limit of pit lane in 50% races, then maybe... in addition to be able use second set of mediums/hards of course)
