Did I say that, where do I even directly come close to saying that? One, don't take stuff personally, and two don't rush to judgement it shows your age. Not to be rude that is. I'd wager I know Aero better and thus I was just explaining why we're seeing what we are seeing.
I doubt it's the arches, and once again we don't know the program end of story, they tested the car at Monza didn't claim any issues, and even if they did have issues they're not going to tell us about it. Same goes for today. As for your analysis how do you gleam that exactly, the set up has been used on in the lmp category for two decades on and off and is a pretty well established aero trick, so unless you have the CFD I think we'd all like to know how you've arrived to this with less then two hours of action.
Also the cutouts that you've mentioned are only on the #3 car unless they changed the front design on the 1 and 2 from silverstone to here after rebuild. Because they don't have the cutouts like that.
