For sure. It's possible I'm just too sensitive to this stuff, but if you work at company of any size..say over 100, and you manage a lot of people...having your HR dept not understand how region, market, company size, etc effect how you should pay, is a huge pain point. These kind of "studies" just make that a lot harder.
Even the custom reports we get are "wrong" if you don't slice the statistics correctly. And a lot of people have no idea what's going on with compensation (salary, bonus and equity) right now, in competitive markets and competitive fields.
Our company is only 700 people and it's been a huge challenge.
