I take your point; I have no idea of the magnitude of this effect in proportion to the total weight. I do wonder if a combination of the airspeed instrument readings, their fluctuation, and fluctuations in the measured weight could be used to estimate the influence of the wind (an application for machine learning?) but even so, that would mean that it would no longer be a simple solution.
