I can get roughly 10-20% from drafting. Over 55 mph the benefits decrease. In my little car, I can feel the difference like night and day. I get back a little too far and I have to stay squarely behind him to stay in the draft. A little to the left or right can throw me back out of the envelope. I get way too far behind and I can feel the buffeting which tells me I am out of the envelope, plus the scangauge confirms this. After 65 mph, I give up and fall back to my grandpa driving. This is just my informal findings.
