   Hi @mattcasters you are correct in that the expectation is that the data has 
been pre-sorted (as required anyway by the step) when using the group by. 
Memory group by would need to do more heavy lifting.
   
   Would be great to enable calculating a moving average for the last X events

   time, value, 2 "day" moving average" 
   T0,10,null
   T1,10,10
   T2,12,11
   T3,10,11
   T4,11,10.5
