you compare your antennas on a calibrated range operated by skilled people?

It's a rhetorical question; no need to answer.

###  DXCC  vs ant performance ?   Thats like comparing a  tribander vs a 20m monobander..
on 20m.   You will works loads of dx with a tribander..or any yagi for that matter.... on 
40-30-20-17-15-12-10m.   So John is correct in stating DXCC  totals  is no indication of ant performance.

##  However on 160m, dxcc  totals probably is  a good indicator of  ant performance..at least using normal modes like
cw  or ssb. 

##  City lots, RX noise, counterpoise, and 160m dont belong in the same sentence.    TX is not the issue, its RX. 
I cant figure out how to possibly get enough separation between a TX..and a RX ant.   Next problem  is.... surrounded 
by noise on 160m.   Orient the dedicated 160M  RX  ant to say ZL land.... and its also pointed at a noise source. 
Now what do I do ?    I see no solution.... except for maybe using a remote RX....or perhaps using some esoteric mode.
