Ok, at the moment all of my Blog posts are more than 24 hours ago yet the Post Bandwidth remains at 36,843 and the tool of course says I should not post a new article (actually it says CAN again, and I saw that you have changed it to SHOULD earlier).
It is really bugging me now how and why is this happening and why the theory does not work in practice, so the only thing that remains is to post a new article and see what happens if my Post Bandwidth will go over 40000 or not.
