Hi, my league ID 102904, I found a very suspusious behavior soft tyre on a other team, is the 2dn race of season, cars not big differences, also drivers are bit similar, but I've got training sesion 6% wear soft tyre 24º Brazil, according with the new update those tyres won't long lasting more than 12-13 laps, that driver runs 17 laps it's 17x6%=102%, he lost on the last 2 laps before pitting only  0.8 per lap, I put together as many variables as I can,DRS pushing, boost and so on, there's any logical explanation or it's bug that this driver found on the game? Mention,  I've been on the game since May 2016, so my experience is not weak. Thank you, please see attached picture.   https://postlmg.cc/Wh7S144w

This has been noted by a few people, I even made a post on here, It's not a bug just the way they have altered the tyre performance in the update. They increased wear but the drop off in performance is linear now so basically a straight line rather than a curve, the wear although higher isn't effecting the speed, S tyres are still performing the same under 25% as they did before the update, this doesn't add more strategies as was the plan.

Thank you Wholly, at the end the update is not what the developers expected then, nothing change, how the heck someone can run near 100% (if no more) tyre wear without "the cliff" performance...

Wear is relative to the tyre condition and even though the relative wear increases now as the tyres are more worn the absolute wear is still way below the practice 6% per lap throughout the race. Before the update the constant 6% wear resulted in tyres of about 35% after 17 laps at neutral push, now it's rather about 28%.

I have to think that 6% is not more to take in consideration to calculate the stint, it's just only foggy info?

Pep
it's 17x6%=102%, 


That's not how to calculate tyre wear, neither on games nor on real life.. First of all it depends on push levels, it also depends on weather. And even he went PL5 all the stint, the wear rate will be like this:

Lap1: 94%
Lap2: 88.50%
Lap3: 83%
Lap4: 78%
Lap5: 73.5%
And so on.. 
Lap 17: can be 10% to 30% depending on push level. 
If you are wondering how i calculated this, there is something called previous race data where you can check your last race tyre wear and fuel consumption. You can find it on home page. Good luck.

Your comment is irrelevant for me,I already know that and used it in my variables, there's no good luck...

I'm not sure it's as simple as the tyres not suffering lap time disadvantage because of high wear, there are other factors at play here. I've been running some tests in a private league and it appears to me that fuel load and the removal of dirty air are contributing to the behaviour we are observing.

Even before the recent changes, in a 50% league I host it was quite common to see teams running softs down to 25% - 30% to avoid doing an extra pit stop.  

IMO the tyres do slow as they wear but this is negated by the fact the fuel load is decreasing towards the end of the stint. Maybe the balance between the lap time penalty resulting from tyre wear and the gain resulting from lower fuel load needs to be tweaked.

I think when the league rules are introduced early next year, for leagues that choose to run a "no refuelling" rule we will see that tyre wear is a handicap. In a no refuelling league, at any point in the race all cars will have similar fuel loads and then we will get to see the difference between a car running softs at 30% and another running new ones. My guess is the new tyres will be faster and the undercut might come into play. 

The other factor is the removal of dirty air. I understand why some managers have welcomed this because of the benefits it brings. Gone are the strange first laps where you might gain or lose 10 places and since the changes were implemented reports of overtaking in the pit lane have dried up. However, because cars are able to follow the one ahead more closely it does seem to encourage the formation of long DRS trains and cars on worn tyres  can sit in the train and be dragged along doing faster lap times on worn tyres than they would if they were on their own.

I'd like to think something like your comment, but the capacity of the tires runs under 20% especially the soft and not seeing losing of performance or minimal, then what's the point of remove dirty air to encorage overtakings if and the end those tires will long lasting with similar performance, it needs a better balance, as you said would be interesting next year about fueling or not.
