首先来一段很长的英文，这是来自SC官网的，官方回复解释了真实的匹配的制度，下面有翻译。

　　Matchmaking

　　You get new player opponents, referred to as Blackguard mercenaries in game, when exploring the map and as occasional invasions on your map. Your opponents are selected by a matchmaking process that attempts to give you the right level of challenge.

　　Your opponents are selected from players with a similar matchmaking score. Every time you get a new Mercenary base on your map, either through exploration or invasion, your matchmaking score increases. Using 'Find new opponent', Headquarters level, experience level or Victory Points have no effect on your matchmaking score.

　　Matchmaking score will gradually decrease over time if you have several player opponents on your map. Therefore, if you are regularly matched with opponents you cannot beat, you will eventually get easier opponents. Only active players' matchmaking score is adjusted down, so leaving the game for a long period of time won't result in the game getting too easy

　　匹配的得分会逐渐减少，随着时间的推移，如果你有几个玩家在你的地图上。因此，如果你经常与你无法击败对手相匹配，你最终会得到更容易的对手。只有上线登录的玩家的匹配分会慢慢向下调节.长时间离开游戏并不会让你的游戏变得更容易.
