Anyone who's ever flown full-size will tell you that flying/landing in a crosswind is just a simple matter of vector mathematics
Exactly - and then compensating with control inputs to counteract the crosswind effect, and put the plane on the correct vector.
Now where was I?...oh yes, control inputs mean drag don't they?
So the if the crosswind effect can be minimized by balancing its effect across the airframe, at least to some extent, then the degree of control inputs should be less.
Which then logically means...You got it!
Less drag = faster plane.
