This is all assuming a constant wind with no shearing.

Exactly, and I think sometimes one CAN get a SSLLIIIGGHTTLLLY or MMMOOOMMEENNNTTAARRYYY better climb rate when climbing into the wind when the wind is increasing in velocity as one climbs. Here's my idea, and I know I read this somewhere, so at least there are two of us in the world that see it this way:

If an airplane is climbing at 70, into a 20 knot headwind, then, yes.. the groundspeed is 50. If the airplane then climbs into a layer where the wind changes to 25 knots, the groundspeed isnt gonna instantaneously change to 45, because the airplane has inertia with its own forward energy. I think the same holds in reverse, hence the "BS" theory of losng lift on downwind to landing.

I am horrible at dynamics, someone might be able to describe this better than I.
