Which figures?

In general, decent NEC models of different antennas should be 
intercomparable. "decent" being the operative word.. it takes a fair 
amount of skill and work to generate good models, especially if there 
are tapered elements, traps, or lumped components.  The other thing 
that will definitely be an issue for a model is anything where the 
feedline or other stuff is part of the antenna, whether deliberately or not.

But, for comparisons of run of the mill Yagi-Uda arrays, with 
attention to segmentation and such, one should be able to get 
comparative data within 1/2 dB or so.
