Generally, back-pressure is not desired for any purpose (in this context).  If I understand correctly, it is an indication that airflow is not optimal- some of it is curling back behind the rider and pushing forward, rather than flowing smoothly around, behind, and away.  It is a type of turbulence that is not only annoying to the rider, but also destroys aerodynamics (leading to poorer performance, poor mileage, buffeting, fatigue, and limiting top speed).

Agreed. I found the back pressure with the stock 2009 windshield to be very fatiguing. It went away with the CalSci windshield. Back pressure is definitely something you do not want on a motorcycle.

The only time I have back pressure is when the regular windscreen is all the way down (stock 2nd gen).  And it can be pretty severe- my jacket actually squeezes me... the sucker is glued to my back and pressing me forward.  Interestingly, if I raise it just an inch, poof, the pressure is gone and the jacket relaxes.  Raising the screen a little seems to let just enough air in under the screen to change everything for some reason.  I don't understand how, but I am just glad it works.

I don't have the problem at all in the summer, because I switch to the cut-down windscreen and there is just air all over.

(EZgirls) One mans' motorcyclist's blowing is another mans' sucking I guess. I always thought it was the wind blowing on my visor that cleared off the rain.
