Still pretty meaningless. All descriptions of type of driving, etc, are all still quite relative/subjective. People drive differently, and the way you drive can have a big impact on MPG. Yes, tracking your own fuel economy can be helpful for budgeting, indications of engine problems, etc. But comparing your MPG to someone else with different mods tells you nothing about how that mod affected MPG. There's no way to know how much personal driving patterns/habits are contributing to differences.
