I am always reading interviews with famous winning sports betters. Some focus on basketball, others baseball...even football. At some point they say..."I compared the sports book lines/odds to my own line/odds. The sportsbook had them at -6, but I had them at only -4, so I felt I had an edge" Or it might be odds, for example they had -180, but I had them at -105. How do you come up with your own lines? Is there a system? Are there standard numbers such as if a team is playing at home or on the road, it adds or takes away 3 points. Are there other standard numbers? Any input would be a monster help! I have searched on Google for a while now and not uncovered anything. Even though it seems to be a standard thing with big time successful sports betters.
