Jakcy, I don't think 10cm appears anywhere in my previous messages.  Was that a typo maybe?

I'm not asking for a change in the rules.  The rules have an inconsistency: the declaration of "size 1" is inconsistent with the declaration of "about 13cm in diameter" -- most size 1 balls are quite a bit larger than that, and there's a wide variance.  I'm just asking for a statement of which of those two declarations will take precedence if we're asked to play with a 16cm ball.  

It would help a lot to know what size of ball we're *really* being asked to play with.  And at what pressure (which is permitted to vary by 70% in size 5 balls, but has a much larger impact on size 1 balls)
