people I know well have been doing this for years. they never go 50-50.Most times they have a side they like and go 65-35_____last i knew it was mostly totals. NBA in the late 90's there were totals moving 6 points. I think due to computer group(Billy W.) Also some college totals and a few college games. if i remember right they did it looking for a min. 5 pts. on totals/ 3 1/2 on games. max was 70-30---60-40 at the lowest. In mid 70's they were the first one known to chart umps. in MLB. they're all retired or dead now,but I know they were living well.Also, let's assume they are worth it. At minus 110, how much would you be willing to risk?
Would you bet more on the steam side and hedge on the peak?
