Hi Clive,

"I meant that it's the compound average rate that is the investment gain we can actually spend. The simple average is just a figure."

From your post I did understand that the Gummy calculator took simple average and SD into account but wasn't clear on whether its results were nominal or real returns (although I haven't looked at the web pages yet so I assume it would be explained there).

Thanks for the clarification. Yes, I agree. As you say, the compound rate is the true value while the simple average is not.
