Is the tire strategy calculation correct ?

[Rucki]

Lets say I have 2 stints and the first tire change would be with still 60% left. If I now change the pace to orange or red I still would come in pit with over 35% to 40% tire left according to the screen, but somehow the game tells me that I would loose time with that ?

Isnt the whole purpose of for example going with 3 stints compared to 2 stints, to then push those tires really hard ?

Depending on the Track this strategy can work, but pushing in this game usually results in your Car in the wall, so driving like a Grandma seems to be the best tactic. Boring as hell if you ask me. I pushed for 1 lap in my last race and crashed within 10 secs. Unbelievable.
There is a drop off in performance, the best way to see this is often by looking at other cars lap times. Once you are losing a few tenths a lap, you might want to pit.

I think that the tire strategy calculations are really off. If I take the preset strategy for Silverstone with 3 stints, (H,M,S) and change the pace in the strategy window for the hard tires to the lowest pace, the game tells me that Im going the end the race 4 Minutes faster... that would lead to going into the first pit with 70% hard tires and beeing ultra slow from the first moment, but the calculation thinks its faster.

look what tyres u can push best. Hards are quite obsolete to my Williams ....yet

I think you need to assume that the strategy screen is taking it's calculations on tire degradation alone.
It's the only explanation as to why not pushing would result in faster theoretical race times. Less wear on the tires means they are closer to new and haven't had as much "wear penalty" applied.
The time loss per lap is an average and I fear this is similar to the vanilla MM where there are 3 distinct wear bands with ever increasing wear penalty. So if you don't take a tire over a certain threshold, the time loss won't be as bad.
Though to be honest, 4 minutes is a huge difference

Some tire strategys that you think should be close can be off on the guide by more that a minute. That might be soft - hard one stop might show as 1:30 quicker than Medium - Hard. Even though the soft would run right to 30% while the med would be pitting later on better tire life. 90 seconds is too much for 2 identical cars.
It's clearly bugged. You then run the cars in the race on different tire strats and the one on medium will stay with the one on softs due to DRS.

the calculations for the Hard Tyre are completely broken. The calculations for meds and softs are close to what you could expect but something in the code leads to wrong numbers since 1.9 patch.

I guess they broke the code with the adjustments for Tyre degradation.
Before the patch, The lap times wouldnt degrade much untill you hit a certain number, around 30%.

Now the laptimes are much more affected by that.

The strategy calculations also don't take rain into account. The game always says its faster to use all dry weather tires on a race where it will rain for more than 50% of the race distance. It completely ignores that there will be rain and that dry tires would be the worst choice during that rain. You just have to know yourself that a rain tire is better, but good luck deciding between inters and full wets before the race starts. Its a crap shoot because none of the graphs in this stupid game have labels on the x axis, You can see there will be some amount of water on track but who knows how much is forecast...
