At a guess, they think claiming that an individual increased revenue by 93% using a simple balancing method is not very plausible, and as it is most likely just and outright lie can thus be discarded as hot air (which is actually pretty charitable).

One objection is of course that 93% is very achievable if the numbers involved are very small, but in that case the statement might just be code for "selling the office sofa" which is often seen as less impressive.
