The scenario I have in mind is this: most of the way through the QSO, you 
suddenly doubt whether or not you correctly copied part of the callsign* - 
for example, was it really K3BU or maybe K4BU?  At this point, you can guess 
that your original hunch was right, log it and hope for the best, or decide 
to ask for a fill until you've reached certainty.

With a zero QSO penalty, you are almost always better off logging the
"almost" QSO, because on average you'll probably be right half of the time, 
and you suffer no penalty for guessing wrong, so it's effectively like 
logging a 0.5x point QSO.  With three QSO penalties, you have to guess 
right in these situations more frequently than 3/4 of the time in order 
to come out ahead.  This makes guessing a very bad strategy for success.


* On phone, this happens to me often - the station repeats his callsign
with different phonetics in an accent that I don't quite get yet, or they
first send their call without phonetics, or maybe they're just weak and
took a QSB fade and you cannot really decide whether or not you're hearing 
"QSL QSL" or something else in response to your suggestion of what you 
think their callsign is....

Everyone in the contest is judged in exactly the same way, and you are no
more or less likely to be the victim of priates or others' poor operation 
than anyone else, so what is the problem?

Sure.

You express a strong opinion on a controversial topic and find out that 
others disagree with you.  Were you expecting something else to happen? :-)
