This needs reasonably predictable markets and the economy to work ... both of which are currently lacking. The market yield and the inflation rate are now just two big blurs and the average answer will be "your FIRE is achievable within 7 to 177 years depending on random things that may or may not happen next".
That said, we still believe it’s useful to focus on what is in your control: contributing to the right accounts in the right order, investing wisely, and minimizing fees. Those fundamentals work in any market, and over time, the ups and downs tend to average out.
Anecdotally, we have found we have two personas: 1) Those early in their financial independence journey. They want to know what to do next to accumulate wealth 2) Those towards the end have saved and accumulated. Their questions are 'do I have enough'
The second persona are running more plans more frequently because the market volatility (and job market volatility) has made them want to check and check again if they have enough.
Markets being more chaotic and unpredictable is just reversion to the mean.
So it doesn't really matter when to release this tool. Might as well do it now.
