Statistics like this are meaningless with respect to any given antenna 
because there's no frame of reference to your location, antenna mounting 
height, and because such factors as the skill of the operator and the 
amount of time the station is on the air, on the right band(s) at the 
right time have such a huge bearing on the results.

The only ways I know of to quantify (or even show) small differences (a 
few dB) in antenna performance are 1) to set them up one at a time like 
N0AX and K7LXC did or 2) to set them up with identical mounting 
conditions, alternate transmissions between them, and compare multiple 
Skimmer spots for thousands of such transmissions, averaging the result; 
and 3) set them up as in (2), but switch between them on receive and 
record and average the differences for thousands of received signals.
