It seems that either the point calculation is off (for some users?) or the point information is not displayed correctly in 'Your Reward Points'. For example, in one user's profile (the name can be disclosed, if requested by a moderator) I see the following information:
Date range: 08/18/2007 - 9/17/2007
Points of date range: 872
But in the details only the following points are displayed:
Forum points - 104 in total (only one page)
Additional points - 20.
Nothing in the Blog, Article or Code contributions.
This is only 124 points. So where are the other 872 - 124 = 748 points are coming from? Is the point system rigged or is some information about how the points have been earned hidden?
