What is wanted is a standing water depth on the track as well as the weather during the practice sessions.
If its raining you do not know how much water there is on the track like it does during the race. So you don't know which wet tyres to pick for the practice laps.
Also more important, when it has just turned dry from a rain spell and you log in, you don't know if there is still any standing water on the track as you did not know there was rain just before you logged in.
This is putting me off playing the game which I would otherwise enjoy.
So please lets have a how much water is standing on the track during the practice sessions.
