You'll most often end up cross-controlled if there's a crosswind component... rudder to keep the aircraft pointed down and aligned parallel to the runway, and aileron to correct for any side drift away from the centerline. When you correct for one, it'll influence and require a correction in the other. Re/ the frequent "bumping" of the controls, the amount of travel for those "bumps" will vary with airspeed...as the plane slows to stall speed (another point for the OP... when you touchdown, the stall horn should be blaring), the controls get increasingly less responsive and it takes more input to get the desired responses. If you keep the controls moving, this helps you feel just how much additional input is needed as the landing process unfolds. As your mains touch in a tricycle-gear plane and you continue to hold the nose off, assuming you're at stall speed, you SHOULD end up with the yoke held full back against your chest, and dependent upon crosswind conditions, full aileron deflection into the wind.... because by that point the airspeed is so slow that controls no longer have much authority so it takes gross inputs to achieve needed and desired results. I am NOT a CFI, nor what I would consider an experienced veteran pilot.
