This is great. The fact you provided us with the information to tweak it for ourselves.
I do however have to note, I do 50% races, and "1.6" was a little too much, so I lowered it to "1.3" and it is perfect.
BUT whilst I was doing it, I noticed that you forgot to change the modifier for McLaren. I did the copy+paste method, and THEN extracted the XML and noticed all teams were "1.6" but McLaren were still "1.0"... So maybe you ought to look into that.
"1.3" for 50% races is perfect. Half of the grid are doing a 1-stop, the other half are doing a 2-stop!
If you want to be the best modder in the world, perhaps add a 50% copy + paste option with all teams set to "1.3" ;)
That would be greatly appreciated! As having to do this manually again once the game updates will be painful haha.
Thanks for the great mod! Keep up the good work.
