The miniCIM output power decreases less drastically than the CIM output power, especially when you look at the first 20 seconds of the curve, which is likely the area on the curve that most FRC robots operate on.

An interesting plot is to plot efficiency of the CIM vs miniCIM by time. Based on the Vex data, I think you will see the miniCIM is about 5% more efficient in the peak power test. When I ran a quick calculation, I assumed a 10.5V output for the CIM and 11V output for the miniCIM since the CIM pulls more current.
