Ive noticed that with a raining track the racing line wet % stays at 0. The other reading that I assume is the off line racing line wet % is the other, and that goes up when it rains then slowly down when the rain stops. Ive tried at Bathurst 12 hr track and the 397 Malaysia track and the racing line wet % stayed at 0. I tried a race at Bahrain and the the racing line wet % stayed at 0 then suddenly jumped up to 30 then came down when the rain stopped and the dry line eventually started. Ive had the real road time scale set at x2 and time scale set to normal. Ive never really taken too much attention to it before but sure both those numbers showed driving line on and off levels of water on the track.
