How to properly test modifications (AKA: don't believe every MPG claim you read)

[j-c-c]

I have made claims here in the past, where following all the parameters to do 'proper" testing just was not practical in trying to control all variables. My test, rather than do a sample to extrapolate, like a 200 mile round trip over the same section of roadway while controlling as many conditions as possible, I'd do a year's worth trips over all the same roads in nearly all conditions say for many tens of thousands of miles as a baseline for an average.
I'm satisfied with my results.

IMO there are two main trains of thought on DIY testing, control methodically all the variables known and/or possible, or make a test controlling what is possible but as long and extensive as allowable, to allow the "random" variables to hopefully cancel in order to achieve a credible result.
Pick your poison.

Don't feed them.

Why not troll them back, they never respond.

I have found from years back they don't recognize the use of color in the verbiage to indicate emphasis on a topic.
