So the system is to take unranked home Favs when they play ranked opponents. Interesting....
Yesterday 2 games met this criteria... (small data set).
> Marq at Nova -1.5
> Oklahoma at Kansas st -2.5
Both Nova and Kansas St. lost.
Lets broaden the system a little and say... Take home teams ATS (when they are favs or dogs) when playing RANKED visitors. Yesterday this resulted in 2-3 record but typically hits ~58% longer-term.
Lets try to improve results. Take home teams ATS (favs or dogs) that are RANKED and playing against RANKED visitors. Typically ~68% ATS results long-term. Yesterday this system was 1-0.
I'm not advocating these system. I'm just indicating what I've read about and tracked for a few years.
