I decided, since I did this before for Berryz Kobo, to do the same for S/Mileage: go to their YouTube channel and go through their promotional videos and see how many I watch to the end and how many I give up on. The score with BK was something like 17-14. Here are the results for S/Mileage:
Indies Singles
Otona ni Narutte Muzukashii!!! - Yes
Suki-chan - Yes
Asu wa Date na no ni, Imasugu Koe ga Kikitai - No
Contradictory - Yes
Major Label Singles

score: 12-4
They kind of hit a wall in Choto Mate Kudasai
but they were able to recover with Samui ne with the Sailor Moon outfits.
I wonder if Kosuga Fuyuka is the only person to appear in one and only one h!p (or h!p related) PV?
