You need to do (cumulative inflation)^(1/ number years) to figure out what the actual average rate of inflation was over that period.
Raw cumulative inflation is really tough to do anything with unless you’re making apples to apples comparisons for two things over the exact same time period. Even then, using average rate of inflation is better because it’s universal.
We got off on the wrong foot. You are actually smart. It just happens to be in a completely matter of technical fact kind of way and I respect that. I will now continue to read the remainder of your comments in a petty attempt to find something to argue with you about. Maybe it will bring out the best in both of us in the process. Write on my friend.
