There are limits to this generalization and it all depends on your 
definition of performance.  Two elements on a 34' boom (for 20M) will not 
have good gain or F/R.  With three elements you can get good gain (>9.4 dBi) 
or good F/R (>20 dB), but not at the same time.  Your statement is correct 
if you are only discussing the difference between four or five elements 
(maybe six also, but I can't think of a good reason to do that).
