Mounting humidity sensors - upright, rotated?

I ask myself if it makes a difference how to mount humidity sensors.

If rotated (20°, 45°) they catch more air but then i believe they need longer to dry.
Like a wet glass you but upside down the moisture is trapped in the notch of the sensor?


I think that would be a very informative experiment and easy to do.
