I think I've brought the wiki page up-to-date with all the results (including Events results from previous years) at
http://wiki.dominionstrategy.com/index.php/List_of_Cards_by_Qvist_Rankings.
Thanks to Werothegreat who appears to have done most of the work in updating the card-cost lists.
Some things in the wiki are still sloppy and maybe could be fixed up. For instance, I don't know why "data-sort-value=~ | -" is used in the tables -- it doesn't seem to sort correctly. Something like "data-sort-value=1000 | -" should work better. Also, the "Card Lists" section is a bit cluttered now, and the headers for each section (giving links to the forum results) are also getting cluttered and are not really that useful.
