Some reasons to measure
Why, in some cases, I measure for personal projects:
the impetus for my measurements is curiosity. I just want to know the answer to a question; most of the time, I don't write up my results.
Also, this random factoid:
As consumers, we should expect that any review that isn't performed by a trusted, independent, agency, that purchases its own review copies has been compromised and is not representative of the median consumer experience.
Remember who butters the bread of whatever “review” you read online.
