[CQ-Contest] Logging Dupes

[LY8O]

I'm logging every QSO regardless is it dupe or not when I am calling CQ. You can never be sure was the station calling you or someone else close to your frequency. I often must to play with rit knob to copy the station calling me even when I use 500Hz filter on CW so you never know what is you potential correpondent looking for in overcrouded bands. Number of years I have used TR software and switched off dupes restriction in menu on CQ. Now I am using WinTest which allow me to log dupes. Same situation is on SSB as well - all we are humans and sometimes lets say simple typing error occures... Or the station you can hear calling another station you don't hear, but on the same frequency... But all duplicated contacts are marked in the final logs with no points credit for QSO so I don't see any criminal in this situation. The only thing is you are losing the time for those QSOs and sometimes it is pitty to see lets say 70-80 dupes in the contest because you can understand you 
simply lost around one hour overall in the contest. But that is the life. And PC+software made this problem very light. So "QSO B4" is out from my transmitting texts...
But there is another problem I'd like to pay attention. Sometimes I transmitting the correspondent call (even when I am not sure I have it correct) + number and I am receiving simple "roger" + number. But when I am asking to confirm the call I am finding out that real call is a bit different from the call we starting the QSO. And if I will not ask to repeat the call - correspondent will not correct it... So what we have in this situation? Unique calls, mistakes, possible deductions, possility to duplicate the QSO and so on. The question is - what can we do to ask the correspondents to pay more attention for QSO qaulity? And no different - is it a contest runner or a simple hunter for something he is looking for...
Thank for your time to read this.

Wow -- I just checked and the software I've been using for a couple of years 
now will NOT allow me to log a dupe.  And, there is no way to turn that 
behavior off.  It simply will not allow entry of a dupe.

The author suggests changing the call sign by adding an additional character 
(such as a question mark) and then going back and deleting one or the other 
from the log.  Which I am not going to do..  So, I guess it's time to look for 
something else to use for logging.  Do most contest software packages allow 
logging dupes?
