I agree mostly with what you said about spotting some flow reversal, however, I disagree about it being an issue worthy of hand-wringing. Ferrari have what is obviously the third quickest chassis but I feel they are much closer to the front in terms of chassis performance than they have been. I think downforce-wise they are near as dammit to the Bull and the Merc, however Red Bull seems to have much better forward traction out of slower corners mechanically, while Merc probably has a chassis roughly equal to the Bull(rb10 probably has a small df advantage) but with a huge power and driveability advantage.
I agree with you, but just for argument sake I never mentioned downforce or differences with others, I commented on the blog-post and how it could have some validity removing the concept of drag or vorticity.
I still see that the move from a thick (greater than 35%) chamber along say 60+% of a chord will cause the effect of abrupt flow separation. Which "could" (notice the wording) explain the loose wobble on the exit of fast corners, considering the side pods accts like a symmetric airfoil, this would alter Cl, with greater Cl on the outer side of the corner, working in favour of centrifugal force. Another explanation would be a change in power displacement on the axels with their engine map, but who knows.
