Calculate %of surface of mesh within tolerance

[[Ja...]]

Hello,

I'm trying to evaluate an organic shape to it's nominal and having trouble with the actual calculation. I've been able to get the heatmap overlay via Surface Comparisons On CAD but haven't found a way to generate the actual calculation I'm looking for. Specifically I want to find how much of the part (%) is within a user defined tolerance. 

 

Any help would be greatly appreciated.
