The 4% SWR studies were just academic exercises using actual market history from 1925 thru 1995 to show a 65 year old retiree how much he/she could withdraw as a % of initial portfolio (inflation adjusted thereafter) and have the portfolio deliver retirement income to age 95 at a 95% probability of success. There were portfolio assumptions as well. Many others have since done the same studies using market data as far as back as 1871 thru present data, e.g. FIRECALC.
So I assume you're planning on a 30 year retirement?
And it was never intended to be a mindless 4% and then inflation adjusted thereafter methodology, course corrections up or down will likely be necessary. Bengen and the Trinity authors said (and reiterated many times)
"the word planning is emphasized because of the great uncertainties in the stock and bond markets. Mid-course corrections likely will be required, with the actual dollar amounts withdrawn adjusted downward or upward relative to the plan. The investor needs to keep in mind that selection of a withdrawal rate is not a matter of contract but rather a matter of planning."
