I didn't mean to poopoo A/B testing altogether.  As I said, I've done 
probably hundreds of hours of it, listening for rx and audio qualities, 
MDS, ability to receive despite horrific conditions, etc.

When you get to a problem is trying to copy the same station on more than 
one radio.  If you can't have both receivers listening to the same signal 
at the same time, you end up with possible variation in the signal being 
received that you simple can't control.  Yes, after flipping back and 
forth a few dozen times, it will all even out statistically, but if the 
two receivers are really, really close, and you want a definitive answer 
as to which is better at hearing weak signals, a stable signal source is 
truly the way to go.

(and nature is never truly predictable :)
