i'm bothered a bit by the fact that in the cartoon animation the earth appears to rotate only two or three times during an entire 25,000+ year axial precession cycle.

I didn't know about axial precession and that visualization was what made it clear for me. Literally a picture that is worth hundreds, if not thousands, of words.
It’s a bit like a camera capturing the wheel of a fast moving car such that it appears to be rotating very slowly.
