We then assume that the quality location are more valuable features for an investor than the agassign a 40% weight to each of the first two characteristics and assign 100 points for a grade of 1; 75 points for a grade of 2; 50 points for a grade of 4.

    wherew is the weight andP the number of points.

    The value of p2 is then calculated as: p2 = (100 - TP) / 100
