I'd also say that if you're not the analytical or particularly academic type, you'd still benefit from absorbing the main conclusions of this study, whether you do it from reading the study itself, or from reading a synopsis from a trusted person.
I'm a bit of a fuzzy thinker at times, but the main takeaway from the Trinity Study for me was that if I have my money invested in a very roughly equal mixture of stocks and bonds, then a WR of 4%, based on the starting value of the portfolio, and adjusted every year for inflation, should last for 30 years (~95% probability which, for many people, is good enough). If you have a lower tolerance for risk, or a longer timespan, or both, then reduce the WR accordingly.
