[CQ-Contest] RIT offset as QRM clue

[Pete Smith]

I've been wondering. When running in contests, I've noticed that sometimes 
stations answering tend to be .1-.2 kHz higher or lower than my 
frequency.  When this pattern emerges, if I check in the "opposite 
direction" I quite often find a relatively loud signal close to my 
frequency on that side.

I'm guessing that people are tuning me in and tending to "lean" away from 
the QRM, and it often seems as if I can improve my run rate by shifting 
frequency a little in the direction that the majority of callers are 
"coming from."

Am I just describing something that everyone else knows about, or am I all 
wet, or is this useful?
