I think their should be a category for fastest brawl ball game, gem grab, hot zone, and possibly others like heist or siege. The easiest would be brawl ball b/c it has a clear timer that stars at 2:30 (counting down).

I the category for finish battle some of the top results are people playing in 7x elixir or in sudden death battles. This is unfair to the player who keep playing in normal elixir (2.8 per second, starting with 5). I think these game should be put in a different category.
