An algorithm that produces NFL and NBA team net ratings serves no purpose if it fails to lead to consistent pointspread winners. A handicapping algorithm must be tested for ATS success before its implementation. If the developed algorithm fails to show a sufficient number of consistent pointspread outcomes throughout numerous seasons, the algorithm must be redeveloped and tested again. The iterative procedure can be time consuming, but the effort can be well worth its weight in gold once the winning algorithm is achieved. But like everything else in life, handicapping proves to be a dynamic process. It is strongly recommended that charts and tables of the ATS results relative to the net ratings and pointspreads be kept and monitored to identify changes and deviations so any adjustments may be applied as required.
