FWIW, there was an aborted attempt to incorporate the R/S calculator into 3dz Studio in the same way that the Normals calculator was Shame it wasn't completed.
The big problem with the existing calculator is that it is a pass / fail program. It either gives you an R/S or it runs until it fills up your hard drive with junk, unless of course you turn it off. It does not analyze the model and tell you which elements fail the R/S.
So what you end up doing is adding two or three elements at a time, stop to check the R/S and if it doesn't pass, you have to go back in and adjust the offending element until it does pass, then continue in this vein until the model is complete. If you add more than two or three elements at a time it makes finding an offending element a PITA.
Not a big deal if you're making simple, box like shapes such as buildings or other TMOD's but anything as complex as an aircraft model becomes a real headache.
For what I do, it's much faster to take a lo-res model with a good R/S, break it up and apply the empty F process to make a hi-res model.
