No, actually, I had other investments that I managed to live off of and didn't start withdrawing from the retirement portfolio until 2013. Also, the first two years I used 3.3%, then when I reached 55 I decided to go up to 3.5%. But those rates aren't including our IRAs yet. If I include those the rate is like 3%.
I retired really early, 39, so I set aside what I considered to be "enough" for a long term retirement portfolio, but I didn't want to tap into it right away, preferring to let it grow for at least 10 years. Managed to last 13.
That's why I use inflation adjusted total net worth over all those years to track how I did, since the retirement portfolio is a subset of all our investments, and we've only been drawing from it for a few years.
So, I'm not sure if I am a good model, although the other investments were actually riskier. Most of those years I was drawing down company stock. If it had ever gone to zero, or dropped really low, I would have switched to the retirement portfolio. Fortunately that didn't happen.
I confess to belts, suspenders, and more belts, and more suspenders.
