As real columns are made from discreete pieces, and that those are not from 
adjacent parts of the same rock, maybe not even from the same quary, the 
weatering is often not concistent.
A strong spot in one piece may be next to a weak spot in it's neibour. So, I see 
no problem in having disparate weathering patterns from one stone to the next.
