If you read the article (available on the C & D website for free as a PDF; google search for the full exact title and it pops up) you'll see that they used a 5th wheel and some inline fuel flow meter. It's hard to measure low-rate liquid flow, especially when it's pulsating like a mechanical fuel pump is.
Assuming that the readings were at least self-consistent, the percent change is what I'd go with, rather than actual MPG numbers. Yeah, that car even driven badly shoudl get 20 on the highway.
