thus, other team should have had more opportunities for win points
no, each team still has the same number of matches versus the other team
for every match marshmallow plays against hot dog, hot dog plays one against marshmallow. Granted they're the same games, but it's still the same number of games for each team. Marshmallow only gets aa win oppurtunity if they're playing against hot dog, which means hotdog also gets a win oppurtunity. One team doesn't just get matches out of nowhere. That just wouldn't make sense
it ended up not working anyway though
this fact should show that to you. The win rates will always be within a few % of 50/50
