But again, I will say: This is for wealthy people. The rest of us do not need a complicated formula. We will need to be super careful not to spend anything other than for the most dire needs. In your example of $160K or so, there is no room for error. That money will not last long. One medical issue can eat up everything. And if that's the median portfolio, half of Americans have even less, or nothing. They won't even be able to tap their money for an emergency. They'll just be screwed. Such is the USA today.

I'm always looking for financial advice not aimed for the wealthy. I almost never find it.
