Wins are measured, not trophies. How many trophies a win brings depends on the brawler's trophy count — high up little gain and much loss, low down the other way round. That count is in none of the battles the API hands out, so this page cannot know it. It answers “where do you win most often”, not “where do you climb fastest”. The two only converge above 50%, and there the order is the same.
Showdown counts something other than a win. There is none there; what is counted is a battle ending with a trophy gain — solo places 1 to 3, in duo and trio places 1 to 2. For this page that is closer to the question than elsewhere, but it does not make the number comparable to team modes. That is why the rating on the card compares within the mode and not across all of them.
