Well sorry, I dont buy that. You can very easily discard laps of the Nords as well. Today I tested 2 setups. Each with a 7 lap stint. In each stint there was an issue or error on one lap. One was traffic, the other my son coming and talking to me. Using live delta I was easily able to see my delta b4 and after the issue and do some "data smoothing", ie average the lap b4 and lap after. Outside those issues the laps are within 0.5 sec over a 8m30sec lap. The level of drivers who are used to do BOP can do consistent laps at Nords. The longer lap is in my view even better than a short one. The Dottinger Hoe separates any aero/drag advantage. Braking is tested in many places. Cornering also over minutes of racing. Fuel consumption too. So nice try but my question remains, how can a car be BOP on the Nordschilefe and not another track? Prefer with an example but a decent argument beats an assertion. Anyone @Guimengo Anyone.
