there is not a site that keeps line history like oddsportal for sports?
and if the numbers dont really matter and you need to know the sport, that would lead me to assume it is not that efficient. Do you know what your avg bet line is and the avg close line and an approx avg margin, so I can get an idea what you 2 are talking about?
