Just a few more comments.
Adjustments to stats are only done to the current days stats at midnight US Central time. So you will notice a drop when the stats roles to previous day. Stats beyond yesterdays stats are not touched.
In the first post you are comparing todays stats shown on your page with todays stats on our page. Realize that there is 6 hours difference between our stats and your stats, so when you posted at 9:23AM US Central time, 15:23 hours user stats was included on your site, but only 9:23 hours was included on our current day stats, so of course it is going to show less. Again our current day is not a good measure. After adjustment at midnight it is a lot better.
Just a couple of things to consider.
