Can someone provide an update on what this all means?

Your data usage:

Period:         23/07/2011 - 22/08/2011
Downloads:   14.78 GB
Uploads:      1.83 GB 
Total:           16.61 GB

Plus yesterday there was this:

2011-08-16    -3,818.51 MB    -14,164.49 MB

So I've just last month increased my data allowance because we were going way over and now it appears that I'm using less than half what we used in previous months, so perhaps I didn't need to increase it at all. Is this meant to be a correction for the past (from when?) or does this negative suddenly turn back to a positive again in a few days?

Even if Orcon are still processing the backlog, I'm not sure how I used -14 GB on the 16th.


Edit: fixed formatting.
