Bill, I'm not confusing forces and accelerations. Did you watch the vid I posted?
I also get all that you posted.
BTW, "spin velocity" is not the best wording as the
spin at the pole is actually the same as the
spin for an Ecuadorian (1rotation/day).
Of course the Ecuadorian has a curvelinear path that contains
both translation and
angular rotation (spin) whereas the Santa has only spin.

as one approaches either pole the spin velocity of the Earth's surface asymptotically approaches 0, so the net acceleration asymptotically approaches g caused by G(capitol G, Earths force gravity) and the person's weight adjusts correspondingly

IOW-
curvelinear translation goes to zero, not the spin.
