Possible easy explanation: instead of aggregating the data for the deck type their top decks are specific decklists, meaning there’s one Facehunter that has the best winrate even if the Facehunter archetype is lower tier.
Individual deck data would be fairly misleading. This is clustered data of many players playing a similar list.
Fair enough. By “similar list” do you generally mean a few cards different, a few cards similar, a majority the same, or are you taking it archetype by archetype?
It depends. If there are a bunch of pirate warrior decks that include the same 25 cards, but they last 5 are any of 20-25 different fringe cards, we would classify that as one deck. If there are a bunch of pirate warrior decks that include the same 25 cards, but the last 5 are either a package of deathrattle cards or a package of murloc cards, we would consider that two separate decks. Someone much better with algorithms and math than I am put together the formula and it wen through a bunch of iteration until we were happy with it. Now it's mostly automatic, but we have to name the deck clusters to make the report readable.
We have a daily report that we don't name the clusters manually, but choose their names by wordcloud based on the name the player chose for their deck. It works pretty well a surprising amount of the time.
