[CQ-Contest] How much is a dB worth ?

[Jim Brown]

I suspect that the magnitude of the difference probably depends on the 
contest. Quite a few years ago, N6ZFO, whose job in pharama development 
included lots of statistics, did an analysis for NCCC saying that 1 dB 
was good for 2.6% in ARRL Sweepstakes.

Pretty good agreement with your work.
