[CQ-Contest] Uniques...actual numbers

[Leigh S. Jones, KR6X]

RE: kr2q comments

I don't place much credence in claims that anyone getting more than a fraction of a percent uniques must be copying call signs wrong.  I can think of a number of situations where the numbers would be significantly higher, especially for DX contests.  

The easiest I can share here would be for activation of a very rare DXCC country, Zone number, or IOTA island.  These operations are often very well publicized, very loud on the bands, and actively spotted.  There can be great motivation on the part of thousands of operators to work these stations once or even six times during a single contest even for those who don't plan to work any other contest participants or send in a log.  Here, 50% uniques sounds reasonably plausible to me.  

I have been at multioperator contests where off-duty operators lined up to work expeditions from a mobile station outside the shack.  These operators know they will not send in a log, know there may even be prohibitions in the contest rules, and yet these contacts don't represent miscopied callsigns, and there really should be no penalty for these contacts in a log.
