When importing constituents even the slightest deviation in spelling, address format, using a nickname, etc, doesn't register as a duplicate when importing, only exact matches seem to filter. This means we are having to manually check for duplicates every import we do, which we do regularly. This is about as slow as manually importing each person and the duplicate detection report is also not particularly useful for this, not to mention how slow it is. A profile that exactly matches, aside from the address abbreviation being Dr as opposed to Dr. should still register as a potential duplicate and at least flag it in some way.
