Help! Numbers do not correlate.

[Charles Evans 25]

I'm currently taking a very crude look at posting patterns over RPGSuperstar since 2008 in terms of raw numbers of posts, and on the first forum I came across, whilst double-checking numbers I found the numbers of post do not add up to what they purportedly 'should'.
This page http://paizo.com/paizo/messageboards/paizoPublishing/rpgsuperstar/previous/ rpgSuperstar2008, makes a claim of '1423 posts in 34 threads' for Round 1 of RPGSuperstar 2008. Actually going into the Round 1 forum of that year to check that figure against the number of posts claimed there for individual threads, I only reach a figure of 1347 posts in total from the 34 threads listed on the forum.
I've checked this 1347 figure twice, once with a calculator and once with a spreadsheet.
Help! What's going on here, please? How accurate are the claims for posts for threads or for forums? Are posts on invisible threads being counted for the pruposes of total numbers of posts, but not the actual threads which they're on for terms of total number of threads?

Well, there are post counts that we know, and post counts that we don't know. And there are the post counts that we don't know that we don't know. And the post counts that we think we don't know, but might actually have written down somewhere but misplaced the sticky because our desk is quite messy and the hamsters have gotten into the catnip.

Non-snarky answer: Post counts are approximations.

Ah....
I'll work on the basis of the figures provided for individual threads then.
Thanks.
Hmm. As an aside have you ever given Donald Rumsfeld oratory lessons? ;)

Okay, I've herded some figures together, and emailed Paizo the results (and some thoughts) if you'll pardon the impertinence....
Ummm. Not too sure what to do if you won't. :-?

Perhaps deleted posts count for the forum's post count, but not for each thread's post count?
