2022 Ford Maverick — hybrid fuel economy dropped with no warning light — buyer question from Orange County

I parked the 2022 Ford Maverick and wrote down what I already tested so I'm not repeating myself. This is me being the wet blanket on purpose.

Write down what you already tried. A second data point from another 2022 Ford Maverick owner helps more than a generic diagnosis. I'd do that before spending real money. This is from a 2022 Ford Maverick in Orange County with 68,500 miles. Not gospel, but it saved me a headache. If this is nothing, great. I want that in data.
