that's that kind of chapter that make me wonder why the author has gone to 8 pages chapter to 4 pages. Also if Hikari's performance is shocking but understandable giving how she does in training, Igurashi's one is more shocking as she not only perform worse than Erika but she don't even goes to Finals. That's said, it was predictable that they don't perform for their first time, it's often the case in Sport manga/anime that the team doesn't really succeed at first.
