Re: QUIDDITCH SPOILERS??
i know. idk why it's cumulative based on scores, especially if they're going for pro quid which uses a different system. i guess because it's way easier to keep track of? and it's a children's book and it's just easier to explain how teams won that way. a lot of the detailed quidditch rules come from Pottermore, which is geared toward the harry potter fans who are older now and might be more familiar with real-world sports rankings.
