I'd be happy to top low 40 mpg average, long term, with an automatic in the same vehicle.

Give the same type of driving and modifications you have, it will beat your mileage.

Exactly. The newer more efficient automatics can use taller ratios than the manual counter part. They can get away with this because the automatic is willing to shift gears for acceleration more easily than the manual driver would, hence the higher fuel economy. Its about how you drive. Given the same efficient driver, the auto is more efficient in this case.

Around town you have to drive it carefully since it wants to downshift at every little touch on the DBW accelerator. I've managed 42 mpg over 5 miles of dense city traffic before, without using many hypermiling techniques beyond driving sanely and timing lights. She gets about 27 mpg for the same trip.

Bingo!
