PROBLEMS

1 - Stats Table Title Bar

This Week: Current Week Stats - 5 Days Total
Last Week: Current Week Stats - 11 Days Total
2 Weeks Ago: Current Week Stats - 11 Days Total

Shouldn't it be something like:

This Week: Current Week - 5 Days Total
Last Week: Last Week - 7 Days Total
2 Weeks Ago: 2 Weeks Ago - 7 Days Total

I see the same issue on your own site. If a basic number is wrong, the confidence in the reported stats rapidly approaches zero.

2 - Bad Stats

I do not understand the numbers that are being reported at all.
We consistently have about 30K posts per week.

For example, in ACP > Statistics I see post counts for the last 3 weeks of:
Week 22 (June 2007) 27296 (partial)
Week 21 (June 2007) 28326
Week 20 (May 2007) 29352

However, your numbers for the same period are:
26835
25114
83889 (yeah, 83K. Is this a 3 week Cumulative Total?)

Similarly for threads, ACP reports:
Week 22 (June 2007) 1523
Week 21 (June 2007) 1516
Week 20 (May 2007) 1629

And your numbers are:
1442
1275
4417 (again, maybe a 3 week cumulative total?)

So there are really 2 issues here:

1. Your numbers for "Two Weeks Ago" are just plain wrong
2. Your numbers don't match vB reports
