I have not made that little since the early 90s.
My mechanic charges way more than that.
While early reflections are very important the rest of this statement is nonsense unless you are breaking symmetry to fix a worse issue.
The rules of physics still apply. This statement however shows a one dimensional knowledge of acoustics (physics). It's the different between knowing what you are doing and parroting rules of thumb from others.
Heed the expert from Atlanta who wrote the book on improving sound. ($500/day per session

On symmetry: Also a no. Reducing early reflections is everything.
The more symmetry, the more reinforcement of early reflections.
