I was using your calculator for the half point and I noticed that there was no box to input the game total for NFL games ... which implies that the value of the half point is the same for a game lined at +3 (with a total of 34) and another game at +3 (with a total of 52).
In MLB, this is not the case ... the +1.5 line is cheaper when the total is larger .. using the same logic, the half-point should be more valuable when the total is smaller, no? ... especially when one total is 150% of the other total.
