Sam,  You can pretty easily forecast the value from now till you empty setpoint and then display the result as a Capsule on the screen as well as a Time/Duration in a Scorecard/Table and have all the results update in real-time  For my example I am going to use some example data but this should look very similar for your use case  Step 1 - Create a Forecasted Value - This function may not work on exactly as you expect on historical data depending on your datasource  $signal.for
