Well, not all the stores in Japan provide sales figures to oricon everyday. Those usually report the numbers at the end of the week. So basically the indexes oricon posts everyday just reflect the sales of the singles/albums in the cd stores that reports sales to oricon everyday. I guess by the end when all the numbers are collected, they figure out that the total sales of singles are usually 1.75 times the index, while 1.7 times for albums.
So this is how we predict the total sales of cds everyday for the top 3 (since oricon does not show the indexes of the cds below top 3).
