bizarre fuel economy reading?

Going to guess 33 miles is to short a distance to test.

You got it, there, brillo .....

Your representative sample is way too small and the experiment isn't replicated.

I reckon that readings (hand calculated) taken over several tanks would give you a pretty good idea of your car's fuel economy.

Yes.

Your sample set is too small for you to get conclusive evidence.

As others have said, your sample is way to small to be meaningful. I keep a log book and record every fill up and the mileage, and I can report a low of about 26 mpg and a high of 33, which seems to be pretty typical. I'm a mature driver who likes to wind it out every now and then when it's safe to do so.

BTW, my car is 100% stock.
