The extra cooking time results in more water loss. I'd imagine in most recipes it'd be nearly imperceptible.
Definitely not as much as half a cup.
Wouldn't it depend on how many cups the original recipe calls for?
I wonder if it's assuming you don't use a slightly lower heat output though despite the lower boiling point?
If you're cooking something at altitude you shouldn't lower the heat - you still need to cook it properly.
