So what you are saying is this:
if filename equals "existing" AND date/time equals "existing" AND file size equals "existing" THEN its a match.
Yep.  And I agree it needs to be better.  You might want to add a feature request at the Official Feature Request/Bug Report Forum
At the risk of necroing a thread, I want to disagree that "it needs to be better" if that translates to "ignores files with small differences in the filename but otherwise the same." From the standpoint of file management, we never, ever want software thinking about this too much. I have encountered multiple situations where i was able to recover from a corrupt file precisely because the software was extremely strict on what it considered to be a duplicate. Put differently, it does not hurt us to have two copies of an important photo, while it can be devastating to have no copies—or one corrupted copy—of an important photo. When importing hundreds or thousands of shots, we absolutely want Lightroom insisting that filename, sixe, and capture date/time be identicial to be considered a duplicate. Otherwise, we want these sorts of decisions left to us. After all, there is a reason that file is different, and it could well be that an atuomated process elsewhere failed and two copies of photo allows us to choose what was the correct image to retain.
Again, sorry for the necro, but I felt this needed to be said.
