Ok, what my system does is calculates a percentage of a certain team covering a spread based on the statistics, trends, and other variables that i put in it. It then gives me a percentage and i base my units off of that percentage.
So in essence if a game has a high enough percentage, i will then make it a play... And the higher the percentage the higher the play.
My units are 1-10, but i wont post a pick that is below a 6* because there is no point, My system finds enough good plays where i dont need to play them all, and when you are dealing with science it is much easier to find VERY strong plays.
So 10* is as high as i go, meaning it had an extremely high percentage coming out of my system to cover the spread tonight.
If there are variables such as Major injuries, and Huge rivalry involved with a game that i cant put in my system i simply dont use those as plays.
Now, dont get me wrong, every single play i put out on this forum will be a very strong play. I wouldnt post them for documentation if they werent. There are tons of 6* and below that i left off, because i only wanted the best on here.
Hope that helps and wasnt just a bunch of rambling. Bol
