Selecting a drawdown rate is a tradeoff between maximizing income and maximizing the odds of NOT running out of money.  

A higher draw rate means a lower chance of a successful outcome and visa versa.  

Choosing a drawdown rate that ignores the statistical odds or not running out of money is a fool's errand.  

We believe an 'optimized' retirement income plan must have a high percentage of income from sources that are guaranteed to last for life - no matter how long the retiree might live.
