Stats anomaly

I was under the impression that the LiveJournal Stats page covered the last 30 days of usage.

I have been keeping usage stats of

pocketlj, my LiveJournal client, since 3 November - ironically almost 30 days ago.

The Stats page says that my client has been used 83 times <quote> 83 Avantgo-PocketLJ 0.6 (8), 0.6a (75) </quote>

However, I've logged no less than 168 posts made using the client during this 29 day period.

Can anyone shed some light on this?
