Scale to New Scale for Cut-off Points

Some client surveys might be using a 0 to 10 scale and others that might be using a 1 to 10 scale (or even 0 to 5, etc.). Either way, the specific questions are the same. From the results, the variance of ratings for a particular criterion (variable) is determined and then I want to convert the variance to a 1 to 100 scale (I could call this the Variance Score). I would like to come up with some rules that can alert us to analyze those highlighted Scores (the "outliers" that exceed a cut-off on whether or not to continue to measure a particular criterion. The rules might be if the Variance Score falls below 50, for example, then they need to investigate whether it makes sense to continue to measure that criterion.

Sounds like setting a +/- point at a say 3 standard deviations for the Score scale but the questions relates to converting the original scale to the 0-100 point scale, if this is viable?
