Are these factors in conflict?

Post #9:

7) If we're in 'quartering' winds, there's no available data for that, one way, or another. A complete unknown.

vs Post #1:

* An 18-mph crosswind has shown a 2.15% mpg penalty @ 50-mph
* A 10-degree-yaw crosswind increases drag by Cd 0.055
* A 12-degree-yaw crosswind lowered the Cd of the Arrivett Brother's NHRA Top Fuel
Streamliner dragster, from 0.20, to 0.18

Or does "quartering wind" relate only to certain degree yaw angles implied by the term?

It seems that the direction of an angling wind will make a difference, just as it makes a difference whether a wind is a headwind or a tailwind. And that an angling headwind will be detrimental, but to a lesser degree; and that an angling tailwind will be beneficial, but to a lesser degree.
