I am a bit confused about how practice, setup and startegy works. Let me give you an example.
Let's say that when I do the practice it is raining. So, obviously I choose the I or W tyres and adjust my setup and strategy for the race according to the results obtained during the practice. If however, on the day of the race it is sunny, than I assume that the setup and strategy are not good as these were based for a rainy day. Ok, one can argue that I can still change the strategy by putting SS, S, H or M tyres but I cannot change the setup (which was based on I or W tyres) as I had finished my practice.
So, if the above is correct, I suggest that the practice, setup and strategy can be done only on the day of the race and if the weather changes again once the practice was done, there should be a specific time to do some practice again according to the present weather conditions. Thanks.
