Maybe an EZNEC grandmaster could do it in 10 minutes, but for the beginner 
nothing can be done with any NEC program in 10 minutes.

Instead of using rules of thumb from ancient history, you can get a far more 
precise answer by simply modeling the antennas under test and the test source 
on EZNEC.  Should take 10 minutes or less.  If you can't go far enough to get 
into the far field, you will at least know the correction factor at the 
distance you can do.  The modeling results also provide a sanity check on your 
actual measurement.
