Accurate analysis of stud walls with cavity insulation

Does Revit / GBS accurately calculate R-values for wall assemblies with insulation between studs?  It doesn't seem like it can without a complex work around involving manually calculating the different material properties and then creating an average to account for differences in thermal bridging depending on material and spacing.  I've searched quite a bit online and haven't found any satisfactory answers.

Yes, the R-value for wall assemblies with studs is taken into account in the GBS constructions by de-rating the r-value of the construction -- including differences between wood studs and metal studs.
