Holy grail or doomed to fail?

Hi there, I was researching and testing some new ideas I had, the results were good but I dont know how it will act for the new soccer season to come, from 826 soccer games I tested, 581 games qualified for the system and all of them were +1 goal, I need to wait at least 5 fixtures played for each team in the major leagues before I can apply it.
