The guys that make millions in large part use their own software.
I used a simple piece of hardware last year for college football season that was suprisingly accurate. I weighted my own opinion most heavily but would use the software to confirm my picks. If both ways checked out, I would place a bet.
Never had a losing week last year and would usually pocket a couple thousand in profit a week. Of course there was alot of lucky but a large part of my success was due to the statistical software I was using.
