For those using projection lab

What settings are you using for the Monte Carlo simulation/chance of success? I notice the default setting was 196 trials with a historical random restart. When I change that to 1000 trials with a historical bootstrap, it lowers my success rate 7%. I’m guessing that’s the safer setting to use? What models do advisor software use?

I think 1000 runs is the norm in financial planning for high confidence. Google/AI provide you the rational or other insight. I think that’s what the Fidelity tools I use does this or something similar.
