This is weird I only see 41 DS games in top 200, and 25 PSP last week. Week before that it was 40 DS 26 PSP.

In Japan DS have over 100 and PSP over 10. But total sales for PSP in Japan was 90,200 and all but 178 copies sold in those 12 games in the top 200. Thats less than 1% out of top 200. In America its over 40%. And I know that almost all sales in Japan are in the top 200 because its a smaller market, and I know Japan is a bad comparison because PSP sales are good only at release and then drop like a rock.

Another thing that is weird is most stores that I go to dont have anywhere near 200 PSP games that they would be selling. The average is probably about 50.

Again I am not saying your data is wrong, I'm sure you know the data you are collecting. I just dont really see how it is possible, all those numbers just seem to weird to me.

So if you say those American PSP numbers are good. I will buy it.

Maybe ioi has less data (i.e. none?) for the Japanese charts outside of the top 100. That would explain the 1% vrs 40%.

I wonder how much of that data (outside the top 100/200) is extrapolated badly. It tends to work much worse when you are dealing with small figures (i.e. say 1 store, sells 1 units of a game - that could be extrapolated to 100 units nationwide - when it could just as easily still be 1 unit). Not much that can be done anyway - except collect more data, which is what ioi is already doing!
