RoyUtah,
I just ran across a TIAA-CREF article that might interest you. Go to:
www.tiaa-crefinstitute.org
click on "Pensions and Retirement"
click on "Published Articles"
The article is titled:
Making Retirement Income Last a Lifetime
John Ameriks, TIAA-CREF Institute, Robert Veres, Inside Information and Mark J. Warshawsky
December 2001
Although the article is about annuities as a component of a retirement portfolio and how it affects portfolio longevity risk, the authors use a Monte Carlo simulator that they attempt to calibrate with a historical simulator. They publish a number of detailed tables with the results from both simulators that you might find useful if you are trying to do sanity checks on your own what-if simulations.
