The system that is included with SportsScan 4.0 may not be the most profitable system that we know of, but it has a number of advantages. First, it allows users the chance to be successful simply by always choosing the home team, or away team, or favorite, or underdog, and so on. In this type of system you only need to achieve a winning percentage of 45% in order to be profitable, and historical data that can be found on covers.com shows that being consistant with any of the above sides will normally result in 45% or better. The system is profitable because the average percent gain on a win is nearly double the average percent decline on a loss. Therefore, simply winning five or even four out of ten will increase your account balance. The second advantage of this type of system is that the interactive markets will stay orderly because there should be close to even action on all sides. There are other systems that would have all users on the same side, which in turn would significantly move the price in one direction and effectively reduce the contract value. The final benefit is that it is lower risk than most strategies, and very difficult to lose your total account balance.
