    Description

      Given the level of documentation on --localThreshold it would be a common expectation that setting this option will cause an immediate switch of queries falling below the threshold. However, as the value is calculated on a moving average, and only done once every 10 seconds, it can take some time for the steady state ping to emerge. This means some queries will hit secondaries below the threshold until the steady state is reached.

      Some documentation on how we reach the threshold calculated value would clear up any confusion.
