A longer distance certainly would have helped....
But check your math.
IIRC, they made five trips of one mile, but they measured after each and averaged them.
At 26mpg I get:
1 mile at 26mpg = .0385 gallons.
.0385 gallons x 6.25lbs/gal = 0.241 lbs of gasoline.
.241lbs = 3.86oz or 109g
At 29mpg I get:
1 mile at 29mpg = .0345 gallons.
.0345 gallons x 6.25lbs/gal = 0.216 lbs of gasoline.
.216lbs = 3.46oz or 98g
That's certainly a measureable difference.
