I use a 4.8%WR (.004 monthly), I do this due to expenses associated with investing, basically giving me about a 5%WR. I also have a "floor", meaning I will withdraw enough for inflation adjusted basic living expenses no matter what.
This works for me as I have intermittent income that can be used to pay for extras, and my floor spending is very low by this forum's standards. I'm also relatively young at 43, so have 20 more years of potential work time. Plus I'm only 25 or so years from a SS check that will fund basic living expenses even at the 72% rate it's currently solvent for. It insures my portfolio never drops below a SHTF number, and can be "topped off" with fulltime work, if I choose to do so for lifestyle reasons at a future date.
A similar, more generic approach to this in on
bogleheads. Given each person's situation is so individualized, I tend to think it's better to look at your entire situation and make your own rules. Take into account how you invest, SWAN, if you think you have the personality that will lend you towards earning money again, age, pensions, etc.
