Apologies for not referencing the WR, 'cuz we didn't know about that at the time, and never used a calculator. Truth is, we made out a year by year budget from our retirement age of 53, to the the year when we'd receive Social Security @62 and Medicare @65. Looking back, we most assuredly withdrew at a much higher rate.
That was about 28 years ago, and we've made it so far, with very little pain. My first post in this thread more or less details our planning logic.
