So for tyre wear I like to take the worst tire % and divide by the number of laps after at least 5 laps. I have an approximate tyre wear for every track but some drivers have different wears. For fuel you got to set it up before the race. I do 5 laps at 0.0 fuel and see the change. Then add fuel based on change per lap. There isn't much you can do about tyre wear and fuel during a race so I don't look at it.
