Quilly there are a lot of things that determine when to get down, if you know you double lunged the deer, 1/2 hour is enough time unless you see it drop in sight, even then wait 15 minutes just to make sure he is expired. The worse the hit, like a liver shot the longer you should wait before tracking the deer, probably an hour or more.

How far will they run? Well they can drop in thier tracks, but that is unusual, mine did this year, but the arrow deflected off the shoulder blade and shattered her spine. With a double lung hit any where from 20-100+ yards. With a liver or single lung or the like, probably 100 yards or more, then they will usually bed down if you do not push them, this is the time you want to give them an hour or so to bleed out.

I will be honest there are others here with a lot more experience with bow than me, I am just passing on what others have said here.
