Moved installation from http://www.thomasrost.no/blog to root for the new year, and realized just after that this made Jetpack start counting from scratch. Same domain, same server. Is it possible to merge? Perhaps a pro-option or something?
Since you have changed your site URL, a new site ID was created for that new site, and your old Stats remain associated to the old site ID.
I have made some changes to your account to invert this process. Coud you go to the jetpack menu, and disconnect / reconnect to WordPress.com? Once you have done so, your old Stats should be back under your account.
I would recommend that you avoid copying this row to your test site, or just replace the Blog ID by your test site ID (47582000) when copying the database, much like you do when changing the siteurl and home values in the *_options table.
