Gomind your dead right. But every experienced 737 pilot knows the AT is pretty hopeless at holding Vref+5 in crappy gusty wx. Its too damn wimpy when aggressive power corrections need to be made.
The Boeing line that the AT can hold speed and doesnt need wind correction factors is fine on a nice sunny Sunday morning with the birds chirping, but it isnt that fine when doing a VOR through the muck with 30kt+ winds varying all over the place.
