[CQ-Contest] Another logging ethics query

[Art Boyars]

Another belated posting from NAQP CW.

I had a small run going.  Worked a guy, but the timing was a tiny bit funny.  Next guy, timing was even more off.  Sure enough, another station was running close to my freq, and my second guy was working him, not me.  So now I think my first guy was working him, too.

I do not want to claim my first guy's QSO, because I'm pretty sure I'm not in his log, and do not want the NIL penalty.  But I do not want to take him out of my log because maybe he really was working me, and he correctly thinks I accepted his QSO.

What do you think I should do?  Is there a way to handle this so I can disclaim the QSO without risking giving him an NIL?
