I just installed a vacuum gauge about a week ago, and while driving at 55 you can see a noticeable effect of drafting, from as far away as 150ft. My vacuum gauge would show higher vacuum as soon as I came into the draft, sometimes as much as 8 in.hg. The more cars ahead of me the farther back I could be as well. So you don't necessarily have to be close to draft.
