I would say 75% computer.
Starting last year I stayed away from the big games cuz u just don't know whats gonna happen. For example, I did not bet on the Clemson A&M game last week.
I don't bet on ND at all cuz of the emotion thing.
And....I bet mostly on the small time games. Like last week I had ODU and UNI to cover on a nice parlay I hit.
I am no expert but this has been working for me.
One last thing...I am finding the over and under are easier than the spread.
