I have a CIO who stated, our churn is no worse than anyone elses, on average. The problem with that statement was that our churn was department specific, so if you looked at the average, it looked great. But if you zoomed in, the highly skilled IT workers were fleeing, and we were left with huge holes that caused real problems.
In the graph you link to, I would love to see that with the top 10%, perhaps even 20% removed. I really wonder how a few hundred people like Elon or Bezos skew the median, plus the thousands of CIOs making 400X what I make.
