Wow. I will admit that I drive under almost optimal conditions, but I did not think you could get a Corolla that low. I think the worst my 1999 Corolla had was 31, but generally above 33 with average around 37 and best at 42 mpg.
(no mods) I thought the newer Corollas were rated slightly more efficient at 40 or 41 highway. ... But I would 120 miles/day @ 40 mpg for 10 miles @ 22 mpg.

Also it should be noted: the SG wasn't calibrated to the car, other than entering the engine size in the setup.

The driving style that got those numbers was pretty non-eco, though. I wouldn't be surprised to find out the numbers are correct, but I can't say for certain.
