For example if there is a 20kt xwind, then during the rotation the control wheel will need to be progressively moved through to about 40 degrees deflection.
I have found that this works quite well in real life.
As a former B-737 guy, the only thing I would have added is that as the rotation continues, the aileron input is adjusted to maintain wings level and as the nose gear leaves the runway surface, adjust rudder input to keep the ball centered. Otherwise, I quite agree with all of the above – particularly, the last sentence!
