Wrong number of total hashes ?

[Mem5]

Hi,

I have downloaded a list of hashes at http://dazzlepod.com/site_media/txt/hashes.txt, which contains 551638 md5 hashes.

cat md5.txt|sort|uniq|wc -l
551638

Hashcat also sees 551638 ("Hashes: 551638 total").
But at the end, it says :

Recovered......: 83818/426429 (19.66%) Digests, 0/1 (0.00%) Salts

Where does "426429" come from ?
I would be waiting for 83818/551638, no ?

Thank you.
