Let me check if I am making an average of 6.25%/ month so far, so I have enough to pay repair the Batsoup Bistro in 6 months.
ALFRED! Do the math and check if my investments are performing optimally.
Mr. Wayne rest assured. I listened to Mrs. Siger in advanced functions, and I know how to calculate the AROC of your investment returns.

Mr. Wayne, it seems as though Fortress of Solitude Inc is offering an investment opportunity. They are promising 7%/ month.
As you wish Mr. Wayne.
Find the instantaneous rate of change of my investment with Wayne Enterprises. If it's lower than the return promised by Fortress of Solitude Inc's opportunity, then move my funds accordingly.
6 months later...
Mr. Wayne, your the AROC of your investments is 3.5%/ month, and the IROC is 5.9%/ month. I recommend you move your funds into the investment opportunity offered by the Fortress of Solitude, otherwise you won't be able to repair your Batmobile or the Batsoup Bistro!
