True, but most of them only tells you which class is in that duration, right? For example, the Kongou sisters take 4 hours to complete, but you have no idea on who you will get unless you're using that spoiler thing on the kancolle tool. Some others like Yuubari or Maruyu have their own duration, so you can tell right away if it's them.
