All large Organizations know how to tweak the numbers to make themselves look good.
I used to work for two accounting firms, back then the major ones fell under the title "The Big 6",
I've worked for E&Y and PWC, they both know how to tweak those numbers and publish many articles saying that they're #1, when neither one of them held that spot. Even the TV companies, ABC, NBC, CBS have a daily war going on about their ratings, especially during the 6:30pm news broadcast. Did you know the anchors have a monitor under their desk while broadcasting live watching the other two networks? Everything is a competition and tweaking those numbers
