This is a cigar forum after all, not an engineering library.

If the terms had any actual meaning, even in the lay sense, I would heartily agree with you. My point is they are purely hype with no meaning. There is nothing, for example, to guarantee that 5X is better than 3X. The gas mixture is whatever the company chooses to specify and pay for.
