There's usually no official chart in week 52 because of christmas/new year
Hm are you sure about that? I notice that there are no week gaps on e.g. Chart Stats (http://www.chartstats.com/chart.php?week=20061223) or polyhex, and their data conform perfectly to other official chart data in all instances I've checked. (The link goes to the week of 23/12/2006, with buttons to next and previous weeks etc.)
