Ah an article by Wade Pfau, he's an incredibly intelligent economist who seems to focus on retirement. From my aggressive perspective I think he's got a conservative bias that may be formed from this last recession and slow recovery but he's got his stuff together. His website is a treasure trove of information - http://wpfau.blogspot.com/.

That table linked above by psu256 is quite helpful for the early retiree looking to get to their age 59.5 money and wondering what SWR is for bridging the gap. Clearly not 4%, as that's designed to last 30 years (95% of the time). If you need to bridge the gap for only 15 years (you are 44), you can withdraw more... but how much? That chart is very helpful in that case.
Thanks for sharing.
That 2.8% SWR for the conservative early retiree looking for 40 years and a 99% safe rate is pretty scary. OMY. Course by the time you're that close, it accelerates fairly quickly.
