If they imbalance the book yes. But in this case the authors got the statistical edge because the bookie is trying to balance the book. What difference does it make if the $10k the bookie needs at 4/1 to balance the book comes from professional better Bob or from long term loser Joe? As soon as the book gets imbalanced again they would have to change the lines again.
