Not taking sides in this debate, but the Reverse Beacon Network can't be 
used to make your case, because there are several variables that can 
very significantly affect the number of times that two stations with 
identical signal strengths are spotted by a given RBN station's CW Skimmer.

The first of these is the format used while running.  Unless CQ or TEST 
appears in proximity to your callsign every 10 minutes, you will not be 
spotted as often as theoretically possible.  A station (or op) that ends 
each QSO with TU NQ4I and nothing else will never be spotted.  At least 
some of the multi-op stations have already discovered this.

The second of these is significant speed variation.  For example if you 
send TEST at 40 wpm followed by your call, even twice, at 30 WPM I doubt 
that CW Skimmer will recognize the connection between the two message 
elements in the decoder stream.  Me, I'm glad, because I've never 
thought that such speed games were a good idea anyhow.

The third is the number of times your call is signed at the end of each 
QSO, and the CW Skimmer validation settings in use at the RBN station 
where the comparison is being made.  Again, signing a couple of times 
every 10 minutes, particularly with a well-known callsign, should 
suffice; using a new, exotic callsign, like one of the multi-numeric 
character calls so much in vogue, the program may want more repetitions 
before it "takes it seriously."
