What would cause an extended period simulation to show balanced flow and demand while storage is still being depleted?

My summary shows demand and flow in balance, but I am clearly losing volume out of storage over the duration of the simulation.  Time steps of the demand pattern and the calculation options match and there appears to be no flow into reservoir elements

  • I did some testing and it appears the "all time steps" is an average of all the reporting timesteps (the displayed time steps), not the calculated timesteps.

    Also, in a model with irregular timesteps (such as a one hour calculation timestep and a few intermediate timesteps inserted at odd times like 13.15 hours), all values are included in the calculation of the average. I did some spot checks in a test model to confirm. 

    I added this to the article.
