Ok, so I was looking at head-to-head tennis lines a few hours ago and was wondering how profitable it would be to throw all favs greater than, lets say, -400 onto one parlay. Even a five teamer probably wouldn't pay much more than even money, and an upset will probably occur in at least one of them. Does anybody have some kind of statistic for the reality of an upset occurring with a fav greater than -400? Maybe something like how many times have these upsets happened in the past three years or so. I would really appreciate anyone who can hook me up with good info.
