I don't really know if this is a bug or just a misinterpretation.
I want to race in China (50%) and change my strategy before the race when i'm still in the pits. I wnat to go Prime-Option-Option. So there are 2 Numbers in the tyre menu, which must somehow be related to the tyre wear.
I assume that the number inside the circle tells me how many laps the tyre compound will last, which would bei 15.7 laps in my case. (Don't really know what the other number tells me).
I want to make my first stop in lap 13, which should be possible, but as soon as a choose something over lap 10 (which is the recommended stop), it tells me that the strategy is invalid.
It's the same withe the option. It should last 8.1 laps, but when I actually select 8laps between stop 1 and 2 my strategy is invalid again.
So either the number tells me somthing completly diffrent, or they are calculeted for 100% races and not adapted to other race length (in 2010 the tyre life fitted to the race legnth), or it's a bug.
As i said i'm not sure if it's actually a bug or maybe i am doing something horribly wrong
