If you applied your method to full scale flying you will end up in places that will not be to your liking. Why do I say this? since the mid 60s I have held comercial SEL MEL and CFI tickets. And as another fellow on here said I certainly would never sign off anyone that thought that way.
If we are talking Xwind as applied to landings then wind gradients are also a factor. Many a otherwise good landing has gone bad because the pilot did not carry a little extra airspeed on final to compensate for localised wind speed variations. It gets to be more fun at night when the visual cues are practically non existent.

I am amazed that people think that there is something different about flying in a crosswind. The airplane doesn't know anything about which way the wind is blowing, and doesn't care, unless its wheels are touching ground. A full-scale pilot actually told me that when flying in a crosswind, he dials in a bit of crossed rudder and aileron trim in order to point the nose closer to his destination, and flies with the ball well off-center. I told him all he will accomplish is slowing his airspeed and his average speed over the ground, but he was far from convinced. I guess old habits and misconceptions die hard.
