Some of our tournaments say they won't start a new inning with less than a minute to play.
Then why not make the game 1:09 instead of 1:10?
I assume this rule exists to help people who might think, 'Oh, crap, do we really need to do a whole 'nother inning when it's so close? Can't we just call it?'
But it's an illusion. No matter how you slice it, there is no escaping the fact that there is an exact moment at which time runs out. Why play games with it? Just set a time and stick with it.
