The amount of time lost in the medium speed corners surprises me. Especially the comparison with Haas - the only real advantage of the Ferrari against the Haas are the power limited parts, so the parts where air drag matters most.
In the high speed corners nobody is limited by downforce - everyone has enough of it for them. Downforce only matters in the slower corners. The Haas being superior there to the Ferrari suggests to me that the Ferrari might have less downforce than the Haas.
According to that logic the RB would be quite close to the Mercedes in downforce, but with noticeable lower efficiency as seen by the time lost on the power limited parts.
Further trends: The Alfa also lacks in downforce - as expected with the even more radical design.
The McLaren seems to be relatively efficient compared to its competition, but with a lack of overall downforce.
Correct me if I am wrong or anyone wants to elaborate.
