20 meters? Really? Even with no wind, that's way too far back. At one bike length off a field, you're feeling the wind. At two bike lengths, you'll be struggling. At three, you're dropped.
Yes, you can feel the difference even at one bike length. However, Cycling Weekly understates "the benefit." We've measured drag reduction much farther than 20 meters. It's just that the benefit, although there, is too small to feel. How far? During hour record attempts on 250 meter velodromes, we've measured the rider drafting themselves. That's cuz even a straw can stir a bathtub.
