Yes, that 'probably' is super important in your post above. When the fuel burns off, faster the car goes, more downforce, more 'pressing to the ground' , alongwith more worn tyres (that decrease ride height) => more plank wear - that's possible too.
So unless we have the 'math' with us, there is no way to predict when the plank wears more, closer to the start of the race or closer to the end of a race.
atleast agree with me that a drooping down front wing on one side without an endplate is going to 'affect' the aero wash to one side of the floor tunnels (the main reason why the noses of the cars are so 'high' in this ground effect era) and we know how sensitive the floor tunnel flow is to 'yaw' ; which indirectly implies that if such a car is faster than the same car that's undamaged, the difference most probably is the driverFarnborough wrote: ↑23 Mar 2025, 21:23The broken wing on 16 was still supporting load into the chassis somewhat competently, the proximity to the ground CAN give it advantage in pure ground effect as aero "ideal" and why they have very strong test for drooping of the wing across the car in scrutineering.
Those effects just cannot be qualified by us to make a driver judgement I feel.
