This is a flawed analysis. It sounds like the "14 point turnaround" in football -- wherein the offensive team is about to score a touchdown, but instead turns the ball over to the defense who runs the ball back for a touchdown of their own -- but it is not analogous. Your missing practice is merely failing to score a touchdown. It does not result in any extra touchdowns or practices for the competition. You really are only 2 practices behind.
