This seems to me like weighing yourself every morning on a scale that is off by 10 pounds. So what, as long as it's consistent you will see if you are losing or gaining.
So (hopefully) they know how their room sounds and by extension they know what sounds better or worse.
You may punch holes in this very easily...don't bother.
Reviewers are "show girls" you'll never get what your expecting.
Use your own brain and ears. 'nuff said.
