But he said that almost as a throwaway, with almost no explanation of his methodology in determining this, nor discussion about how common this problem might be.
Tl;dr He actually tested each cycle, timed what it did, and measured the energy with a Kill a Watt. He also found the repair manual, which included a diagram of each cycle that matched his tests.
His ultimate finding was that all of the cycles and modifiers did wildly different things, none of which correlated in any way to their name.
My dishwasher came with a booklet that showed energy and water consumption for each setting. Eco mode is about 20% - 50% more efficient in comparison to the other programs.
