(not having read the entire post) ... I would have thought a more 
relevant factor would be that the major Landmasses are in the Northern 
Hemisphere and the major populations are in the Northern Hemisphere ... 
so whilst the potion of 'The Globe' lite would be similar, 'the 
landmass' and 'population' portions lite would be less .... maybe not 
drastically, but still less!
