Okay, so I am building an appraisal system that will allow any number of metrics to be included in the appraisal and have any kind of percentage of the overall appraisal score. And those percentages equal 100% prior to scoring. However, a person may rate a metric as not applicable thereby removing the percentage of the not applicable metric from the overall total of 100%. The percentage of the not applicable metric must be proportionately redistributed over the remaining applicable metrics. Example: Assuming a scale of 1 to 5 
Metric         Weight     Score  Weighted Score
Leadership     40%        2      .8
Punctuality    20%        2      .4
Cleanliness    30%        2      .6
Responsiveness 10%        2      .2
Total          100%              2

However, if we remove one metric entirely by rating it NA then our table looks like this 
Metric         Weight     Score  Weighted Score
Leadership     ?>40%        2      ?
Punctuality    --           NA     --
Cleanliness    ?>30%        2      ?
Responsiveness ?>10%        2      ?
Total          100%                2

How do I proportionately redistribute the 20% across the remaining three metrics to have a total of 100% and all weights are still proportional to the overall score distribution? Thanks for your time and help.
