Team format?
I think people underestimate how long they spend talking each shot over with their teammate.
Yes, even when you play alt shot and the pinehurst/chapman formats you go over strategy on which shot to hit or what you want left on the next shot. A minute or 2 doesn't seem like a lot, but do that 18 times and you just added a half hour onto a round that you don't normally have with your weekend foursome.
