my opinion is no, accuscore is not worth joining. in almost every game, the percentage of team winning (is equvilant to the - money line amount) or in spread sports, projections are almost right on the spread every time.
example boston say the line is -210 and that correlates to like a 63% chance of winning in the betting world, accuscore will have their prediction at 64%.
now say in football, bears -4 vs packers, accuscore will have a project score of like 21.7 to 18.2 or some shit like that.
