That was a great win! Glad to see Creek's more sensitive side in full display, it's so undermined by the fandom flanderizing her as the obsessed mommy.
Also, I knew the writer did proper research into sports psychology the moment they introduced the Zone (there was a diagram behind Tamamo iirc), but for them to even bring up habituation to control the Zone is so cool. I remember making a case study out of that in archery, and many pro archers did suggest finding or creating a habit that forces you into 'the groove' when competing.
