Excuse me for not responding for so long. I don't clearly understand, for what is needed stats block on dashboard page. On first page block shows overall site visits. On course page it shows course visits. What should it show on dashboard page?

What should it show on dashboard page?

I deployed this patch on some of my moodle instances it logically show same stats as on frontpage because $COURSE->id = 1 on the dashboard. I think this behavior is fine.
Indeed on most of moodle instances i use the dashboard/my as default page and as administrator i like to have quick access to several data such as usage statistic ASAP so i add several blocks (like graph_stats) on it for this.

Note : I think this PR could (and maybe should) be completed by an upgrade into db/access.php to prevent all users to add this block on their dashboard by default.
