On the Williams documantary that was shown on NatGeo, last year, it was said that on a good day of development with substancial tweaks to the fw, they can gain a tenth with it
I don't know if this little tweaks would account for a full tenth, but maybe the half one you mentioned
Well, I pointed some coloured arrows into all the visible changes for those who aren't on a mood to look for it(well, not that it takes much effort to spot it all, still here it is):
_The red one appears to be the most significant to me because those curves are vortex generators and we all know how much vortices affects aerodynamics. For some reason, they are gonna now
_A gurney, blue/green arrow, on the inner edge of the upper plane is now used and with a "odd" black bump under it(orange arrow)
_The yellow arrows points to the several differences in the planes' connector/adjusters
_finally the small vertical pieces pointed by white arrows. Don't know if those would account for any significant difference, at all, but hey, they must know what they are doing
