Hi thez9zon,
I'm not a test pilot and shouldn't really answer this one but am in the grey beard category and was happening past.
Maybe it is the up-wash you should be considering ahead of the wing.
Air at the lower velocities being incompressible (mostly) sends a forward pressure wave that influences the direction of the approaching airflow.
A visual representation of this would be the rising bow wave ahead of a large ship.
Hope that helps until you get a real answer.
