Interesting language here they refer to it as both their High DF wing and their
Highest DF wing....

Perhaps the high DF wings of old (And Monaco) are gone now with the additional DF from the floor, but these wings are closely related in performance and will likely have some overlap, hence the testing of the two at Suzuka to see which works best, this is very different from the old High DF wings and ones used at Monaco and other tracks by the other teams.
An example of last years Mclaren wing, mare aggressive than this years.
So it is all relative of course but those Singapore wings are noticeably smaller than both Last year and Monaco, apart from Mclaren who did not produce a specialist High DF wing. Even last year Mclaren ran with a much thicker and wider bottom element but the all black wing is a bit hard to see on a dark track. Again it didn't have the winglets and for that reason it was also producing more DF. So relative to other wings we have this is our high DF wing (Upper Med), but it is not a high DF wing relative to the DF they can efficiently run if they choose to or wings that have run this and last year. In that range these wings are quite sensible, hence I refer to them all as being closer to med downforce RW. And this may be because of the grip the floors themselves now produce, as well as the track layout changes.
Merc did not run their Monaco wing at Singapore because they don't need that downforce from the wing here because it didn't need that high a DF wing, so they have that blunt trauma DF available but they didn't use it because it wasn't suitable for this track, like the other teams at Monaco who did not bring those high DF wings to Singapore..
The cars are too good now, we don't need actual high DF wings anywhere but Monaco.
