   Excellent, it is linear now.

   Because it is linear you can just use standard linear regression. It should   
   be definitely better than any other least squares approximation.   
      
   But the actual problem as far as I understand you is that approximation is   
   only the first step. After that you should blur the approximation so that   
   it will fit all data exactly. Then you will have V and C fuzzy.
