Well, don't forget about the shift of Earth's magnetic poles over the eras. What goes around often comes around...eventually. ; )
Seriously, though, I once read that there's a very slight vertical axis twist in G1 from bottom to top which was proposed to be due to errors in construction due to the slight local change in gravity caused by the increasing mass of the structure.
