Yes, and 21+ dB (including ground reflection) is hard to come by any other 
way.  I was thinking more in terms of a contester making the choice 
between, say, 16 dBi from a long-boom yagi versus  the same gain from a 
stack.  The stack would not only have a wider azimuth beamwidth but also a 
wider elevation beamwidth.  Whether this extra width is "useful" is much 
harder to test, or to prove...
