I don't log RTF's as XC, but that's just so that some some anal clown at an interview doesn't ask me to prove that I went 50 NM before turning around.

Logging XC on a RTF (even legit) might cause an interviewer to suspect that you just let "autofill" populate your logbook rather than thinking about what goes in there.

Yes, I've heard of "press to test" stuff like that happening at interviews
