When I have played around with drafting on a bicycle (with a friend, not in a race), we found that the best spot was with the front edge of the front tire about even with the lead bicycle's rear axle. To get that overlap, you have to go "diagonally" somewhat, of course. But you really want the two tires as close to touching as possible, to get more "behind" than "diagonal".
