Long term records is what you should be checking with weighing to current periods, sports or subsets, whatever you are comfortable with. Example: CFB game totals vs sides, half time vs full games, last 3 years vs last 7 years. It's nice to be 6-4 last ten, a lot better to be 220-180 over last 400 at -108 or -110 odds. But that's not the records most want to provide. GL
