What I find amusing, is the statements that I have highlighted. How do you define the boundary conditions for them. They are very vague and have arrived without any scientific methods to it (probably based on vague theoretical understandings), whereas it might actually be a desired thing for Mercedes! Who knows. It's not that they can't get an understanding of the flow structures, without running it on track. Now what is the limit? How do we know? The purpose of tightening the sidepod package, is to feed as much high velocity air as possible and in as much uninterrupted manner as possible to the wing. In that way, it might even be desired.
I find it difficult to understand that, if someone like @Vanja can derive a conclusion that Mercedes have pushed the wing over the limt, killing the diffuser and floor performance AND it is bad and it can't provide mid-corner-behavior-predictability, how ignorant could Mercedes folks be, that a thing which so easy for an average normal forum member to understand, is something they haven't despite possessing multi-million resources.
It's a good thing to present the thoughts on what one sees through the car pictures and present the guess work in more humble manner, than to outrightly conclude that it is bad without having done any practical study of that guess work.
Laddie, so many words, so little understanding. But I do appreciate your attention to my statements, you never forget to comment on them. Also, stating things like
probably based on vague theoretical understandings

is just a wee bit degrading towards f1technical.net and it's owner, having directed them to a moderator (and to one of technical writers). It's not my intention to justify my statement, as I see no need to justify facts.
What turbof1 stated, and you haven't read or understood properly, is that this is testing and we don't know if Mercedes pushed this design over the limit intentionally or not. Maybe they weren't sure if there would be as much separation, maybe they wanted to confirm how much there would be - we do not know. What we can say is that said separation on the picture in question is very, very likely too big and over the top. Separation causes wing performance drop and, as a consequence, diffuser and underfloor as well - as these are both very dependent on performance of the other. And these are facts.
As this is going far away from comments about the car, I hope your reply will be only about the car. If there are some other things you wish to discuss with me, please do so via private message.
