I think the general method is absolutely fine, the only thing that might be wrong about it is the estimation how many percent of standalone Move controllers were sold to people who already own a Playstation eye and not as secondary controllers. That number can currently only be guessed I think, so it could be quite a bit different.
What I find quite surprising by the way is the significantly different ratio of starter packs/standalone move controllers.
In Europe they sold 70000 starter packs but only 30000 move controllers (233%)
In the Americas they sold only 50000 starter packs, but 35000 move controllers (142%)
I would have expected that the average number of additional move controllers bought is rather similar between Europe and the US.
