Good idea. Couple of comments:
1 - your bands are inconsisent. They should have the same range variance in each. 75-79 in particular seems odd. If it turns out those narrow bands favour one or the other console (say Kinect has one 76 game vs 2 74 Move games) you're going to ignite a lot of arguing. Make it 49 or below, then usual 50 to 59, 50 to 69, etc. then 90 plus.
2 - I agree on EyePet and not including Heavy Rain, etc. This is about launch titles for me and Move/Kinect specific titles with EyePet the clear exception to the rule in that it is a motion control title and clearly benefits from the Move addition - in short, EyePet is a Move title that was bundled out the door in Europe early before Move was fully formed so I think it's useful to see how it scored as a suitably motion centric casual title.
Although it's already obvious, this should make clear the alignment of proven genres/approaches for motion control from Wii to scores vs 'experiments' that went wrong or titles that just plain shouldn't have motion controls forced into them.
Try to be reasonable... its easier than you think...
