The ADMMass thorn calculates the ADMMass by the spacetime, but not 
including punctures. The best way to go about that is to exclude the BH 
interior from the ADMMass calculation (there are already parameters for 
that), and to add the BH mass returned by the AHFinder (AHFinderDirect) 
to that for a total mass.
