Funnily enough that's a point (no pun intended!) I was going to raise, the use of a natural cup like hole to start it off. If they did and there was more than one, the 'pattern' produced would have been random and may not have been important to them, just the cupmarks themselves. Does that tell us anything other than the obvious?
