Hi prnewbie,
I think you haven't fully considered what the term "up to" means. The term "up to" as it is usually used in advertising, means _anything_ up to the stated maximum. Simply put, it could be any of 1x, 2x, 3x, ... , 18x.
Unfortunately, this is the kind of mistake that marketing departments count on. People have a tendency to delete (not hear or conveniently forget) the "up to" portion and only hear the 18x portion. Also unfortunately, this leads to customer dissatisfaction when they don't meet their self-inflated expectations.
