This occurs when it will erroneously recount a duplicated chuck. Thus the count will be off and the number of not received chunks is proportional to the number of duplicates recounted.
I wrote a script that will automatically check for this pattern:

Segment #1097 was erroneously retransmitted after it was received!
Segment #1096 was erroneously retransmitted after it was received!
Segment #1095 was erroneously retransmitted after it was received!
Segment #2325 was never received!
Segment #2326 was never received!
Segment #2327 was never received!
Only 2325 out of 2328 segments were received!

As you can see, three segments were recounted causing three segments to never be received.
