3 mistakes you made
1. 9 days not 8!
2. Sales are 517k in the US not 550k (you mixed up NoA with US) http://www.vgchartz.com/weekly/41609/USA/
3. Sales for Nintendo games aren't 10%-15%. All games vary but avg out (at least on 3DS) to about 3%-5%
Srry if i come off like an ***! Just being honest O.o
Here are facts though
Digital sales with 12 days in the US has reached over 100k
Also here is my comparison thread to Spirit tracks
