I have access to and have been performing detailed analysis of a much much larger data set than they have access to. Location, salary, which job boards you use, and how high you come up in the rankings of which job boards you post to will have an effect that absolutely swamps their "magic number".

When someone has a proprietary number that they show you to describe something - "Textio Score", "KLOUT NUMBER", etc, you're being sold snake oil.

Don't waste your money.
