I do not bet. I just want to do that because I like to predict future events.
That's good, but like I said it takes more information than a number.
"The more you know, the more you win" is an old gambling adage. Although it works for about anything.
Some time ago I came across a book of Biorythyms. There was a person that said he used it for sports betting, and quoted some ridiculous win percentage. I knew better, but checked it out.
According to birthdates it looked at physical, emotion, and intelectual patterns. It's a calculator that you put in B-dates according to groups and then get the forecast. So I loaded all my MLB pitchers and tested it. If you were on the fence regarding two opposing pitchers it might break a tie for a decision, but I couldn't see much advantage with predicting wins.
This might improve your accuracy At least it might tell you if you're compatible with the person you've been married to for years. LOL
