Interesting POVs. While I use spreadsheets to analyze, it's easy, I usually learn something worthwhile with each exercise, and it takes a trivial amount of time in the overall scheme of things given what's at stake in $. The OP took less than 45 minutes, and I thought it might interest others, though I did it for myself.
And there's a large playing field between 'multiply by 4% and be done with it' and 'analyzing to the nth degree' - few here probably go to either extreme, especially the latter. I think am somewhere in the middle, simply trying to make good fundamental choices as there are many variables and unknowns as we all know, and some known changes that occur from time to time, like tax code. By all means to each his/her own...
