driver changes after some time opinion for the configuration

I have the configuration worked out and saved. The driver's response was perfect but the time was very bad. Some time later the driver's response was different. Wings and heights were completely wrong. Unfortunately there were no more round left. Came so far 2 times before and is mostly noticed when changing from app to laptop.

It's usually caused by the weather changing. Rain may have stopped just before you did your run but the track could have still been wet.

As I B explains, when the weather changes, it seems the drivers update their feedback. This is why I always wait until 10 minutes before the race to perform my practice laps.
