Ask yourself why they choose to not model the antenna. Often, when people

I think they did model it, and compared the results against actual
hands-on observations, readings, contacts, etc.

This is why they make the claim NEC is missing something ... they simply
believe their eyes, ears and meter readings and signal reports ...
