Maybe the numbers are a calculated guesstimate of what sales may be, based on the answers surveyors give? I have no idea. Honestly, I never understood what exactly Ninki does.
The weekly rank is good, but *sigh* there goes the whole "everybody keeps doing better" trend. But if the total ends up being close to Golden Chinatown / Sayonara Usotsuki no Watashi (36k) I'd be happy.
I think that's why coupling tracks are helpful... It makes people want to buy the single more, especially if there are 2 of them... (People would buy the single and get a coupling track too, much more enticing than just 2 songs you can listen to online)
NoBerryz,NoLife. Please people, I'm a "he" not a "she".
Come on Berryz! Get your shit together ! An egg group who hasn't officially graduated sells more than what you can't even reach in 10 YEARS! Pitiful.....
