"It sounds like you've got so much to think about during battle.."

Not that Madoka doesn't when she's doing her archery, but she feels like she has a little bit more time to think there. Most of the time when she's shooting things, they're still pretty far away. Even though you still have some room when it comes to a long weapon like a spear, the enemy is still much more close up..

Hence why she sounds kind of genuinely impressed as she looks at him to say: "You can think about so much so quickly."
