Wikipedia's graph of Obliquity of the Ecliptic ranged from 22-13-44 to 24-20-50 over five million years. The graph was calculated numerically.

Now Dr Charles Hapgood professor geology Univ New Hampshire provided evidence through rock magnetism that the location of the North Pole has moved three times over the past 80,000 years

80,000/70,000BC - Yukon to Greenland Sea - 62/72 degrees latitude.
55,000/50,000BC - Greenland Sea to Hudson Bay -72/60 degrees latitude.
17,000/12,000BC - Hudson Bay to Current location -60/90 degrees latitude.

Does not Hapgood's findings suggest that Wikipedia's graph of Obliquity of the Ecliptic has not taken into consideration actual radical changes in determining its theoretical conclusion?

Besides the fact that his theories are not supported by science today (he was not a geology professor either), his theories have no bearing on the plane of the ecliptic.

His ideas were that the lithospheric surface (the continents) slid over the underlying earth.  So in his model, it's not that the ecliptic is changing, it's that the continents are moving around.

But the real point here is that there is no need to consider his theories.  While they could solve some specific issues, they do not fit will with many other points of evidence.
