  1. Scoring Formula The proposed unweighted scores are calculated by subtracting the sum of relevant unweighted coefficients, divided by 10, from 1 (Perfect health). The resulting values are linearly transformed to the same scale (min = -0.59, max = 1) of the weighted scores by multiplying them for 1.59 (the range) and adding -0.59 (the lowest possible value). For example, the algorithm for computing the score for the health state 21223 is: [(1 - ((1 + 0 + 1 + 1 + 2)/10)] · 1.59 - 0.59 = 0.205
