"You have made all of us spreadsheet guys very happy!"

That was one reader's comment about my recent stress test of the bucket system for retirement-portfolio management, which included a link to a spreadsheet detailing the cash flows in and out of a model bucket portfolio. The model portfolio performed well over the challenging, but admittedly arbitrary, time period of 2007-12, and readers said they found it useful to see the logistics of retirement-portfolio management from year to year.
