What is the interaction, if any, between the retirement portfolios constructed using Monte Carlo planning and the option to annuitize in the Retirement section? I read the Monte Carlo analysis as effectively self-annuitization via smooth withdrawals if one leaves the percent of assets to be annuitized at 0% and 100% non-annuitized to be spent in the Retirement section.

But what happens if one chooses to annuitize all or part of those retirement accounts? Does one need to specify in the Monte Carlo section that those accounts are no longer held (i.e., blanked out) at the date one wishes to annutize and for the years beyond to give accurate results? Why is there only a stock/bond option for variable annuities when the Monte Carlo simulation permits percentage allocation across a wider range of assets? Given that many variable annuities are held in diversified portfolios this seems limiting. I reread the documentation but this remains opaque to me.
