This was for college football
Does any one have opinions or links to how many games you need to say that your theory is statistically relevant?
I back tested a theory and it went 123-87 from 08-11. So 210 games at 52.5 games per year. Is that enough to have any confidence in it this year? It hit 58.6%, best year was last year 30-18, 62.5% worst year was 7-6, 53.8%
