What I'm hoping to see at some point is an actuary knowledgeable in life insurance mathematics take a crack at the topic.
Obviously you can derive the amount of time worked for any number of accumulated expenses (1/withdrawal ratio) from the starting capital, interest rate and savings rate  see below  but that doesn't factor into account mortality and the desired ruin probability / probability of exhausting the stash before death.

This is a great find, thanks Jacob, I think I'm going to rewrite this into an Org file for my own reference; it should solidify my understanding better.
