Something else odd I just noticed - you know how when you've just posted, your profile picture isn't visible next to your post? The medal count is different too.

Currently I have three gold and four silver medals.

When I have just posted, I have one gold and four silver medals.

The lack of image suggests it hasn't accessed all your data to display it on the page yet - so from that it suggests (again) there are definitely multiple kinds of data being computed into it. Possibly whenever the page loads.
