If the companies just add more engineers, this shouldn't affect the metric (unless you also count the tenure of people who are actually still working there, but that doesn't sound like a good way to estimate churn rate...)

If that's the case, it seems there is quite a bit of confusion about this: https://www.bloomberg.com/view/articles/2013-07-29/why-are-g...

You didn't quote turnover figures, you quoted average time on the job.
