I have produced a predictive sports model for American sports.  Using multiple factors I can quantitatively handicap games and come up with a solid number.  I then compare my number to the market lines and if there is a high enough of expected value, fire away.  

If you join me you don't have to worry about my mental state, pressing, going on tilt, or any of that nonsense.  The model has no cognitive bias and will produce the best results over the long-term.

I do wait until close to game time.  The reason is simple.  I need as much data as possible about the weather and players starting.  That is why you will see the picks released around two hours before game time.  They don't come all at once because as I get new info or lines move favorably, we continue to fire.
