No, it is not. I think the difference reveals at Sousenkyo the most, especially at the voting results of Senbatsu or Kami7 (1st-7th places; it’s said that it’s difficult to enter for new comers). From 4th or 5th election the total number of votes increased a lot and something had changed. Though it’s just my opinion…till Undergirls (17th-32nd), whether the members can enter the rankings depends on whether the members have a lot of casual fans at the moment, or have very enthusiastic and core fans even if they are few. I guess the rankings till 10th place are also same as that. But whether the members can enter Kami7 depends whether the core fans support them enthusiastically AND in addition to this, widely and shallowly whether a lot of fans who buy only one CD - those are really near to the general people – will vote for them.“
