 ## Expected time-steps/hour
 
-The following table outlines expected performance in terms of the number of time steps per hour 
-(rounded to the nearest hundred) for various problem sizes (grid cells) and hardware for an inviscid, 6-equation (`model_eqns' : 3`), 3D simulation.
-CPU results utilize an entire die.
+The following table outlines expected performance in terms of the number of time steps per hour (rounded to the nearest hundred, higher is better).
+A 3D inviscid, 6-equation (`'model_eqns' : 3`) problem is solved for various problem sizes (grid cells) and hardware.
+CPU results utilize an entire processor die.
