Yes, this is the proper name of the ability. However, as far as we know (that is, according to what Aaron has revealed about this ability), it does NOT alter the chances for an event to occur, but rather reduce the odds for a given event to target this system. So if only one system can be targetted by an event, it will be the target no matter what. Likewise, if all the systems have this ability at the same value, they will not do anything.
Here is the link for the thread in which Aaron explains how it is supposed to work.
