i will show what the system is and just list the final results instead of each year
lets start going from huge negative to any plus which ex ample would be say the Eagles lost by 10 points as a 7 point chalk thats negative 17 pts vs the spread next game they win as dog of 3 by 5 points so thats 8 points postive and 25 points in one move .... even if didnt go plus but say up to -2 or -1 it's still a gain and teams will fail.
