Percentage increase in MPGs for simple mods?

I recently added partial grille block to my minvan, and in a half tanks worth of driving saw the difference on the tripometer. So I did the same thing to the Max and noticed the difference on the scanguage.

While I realize a grille block will have varying results according to average speed and size of grille opening etc, it struck me that I increased the mpg possible from my van about 10% with a bit of old vinyl siding and some zip ties. Are my results just not completely tested, or is a grille block (or other smaller mods) much more effective than I am led to believe?
