I've set the final score for 'do' at 66% to reflect the idea that there should be strong positives in favour of commitment.
The score for each question is the product of the answer and the weight. The maximum score possible for each question is the product of a 'yes' and the weight.
So, for example, if the weight chosen is 'Very Important' (3 points) and the answer chosen is 'Maybe' (2 points), then the score is 3 (3x1) and the maximum possile score is 6 (3x2).
The total score is the sum of all scores. The total maximum score is the sum of all maximum scores. The final score is a percentage of the former over the latter.
The form displays the score rounded down to the nearest whole number.
