[Dx4win] DX4Win/LoTW help and advice please - Again!

[Pete Smith]

I'm confused. Here is a section from a relatively recent activity report 
from LOTW in which I inadvertently overlapped with a previous upload.  
LOTW appears to be reporting a replacement, not an additional duplicate 
record.

2008-11-20 21:27:29 LOTW_QSO:  QSO record QSLs a contact
2008-11-20 21:27:29 LOTW_QSO:     QSO: N4ZR N6HC 2008-01-12 21:53:20Z 20M CW
2008-11-20 21:27:30 LOTW_QSO:  [Additional QSL notices suppressed]
2008-11-20 21:30:29 LOTW_QSO:  WARNING: QSO replaces existing record
2008-11-20 21:30:29 LOTW_QSO:     QSO: N4ZR ZC4LI 2008-03-15 12:08:28Z 20M CW
2008-11-20 21:30:32 LOTW_QSO:  WARNING: QSO replaces existing record
2008-11-20 21:30:32 LOTW_QSO:     QSO: N4ZR EU1PA 2008-03-15 12:08:55Z 20M CW
2008-11-20 21:30:32 LOTW_QSO:  WARNING: QSO replaces existing record
...

But at the end of the report, it says:

"1919 records were duplicates"

But my DX4WIN says 102966 QSOs, and LOTW says 106,867 records, which would seem to suggest that Larry is correct, and I have overlapped at least once before.  But then why say "replaces existing record"?

73, Pete
