Yup. It's what I call "digital thinking". As long as you can measure something, there is always a winner and a loser. Digital thinkers don't care about the size of the difference.
Bicycle people LOVE to brag endlessly about miniscule equipment differences. Ceramic bearings are going to be the next big thing.
