Thoughts on the number of runs in Monte Carlo simulation

Yaohua2024

Hi, I have been reading up on 3 sigma from this wikipedia article. https://en.wikipedia.org/wiki/68%E2%80%9395%E2%80%9399.7_rule

In this article, you can see the following table that lists the probability of occurrence for different sigmas. 

If my PDK models with plus, minus 3 sigma then does that mean I just need to do 370 runs in Monte Carlo simulation to capture a full picture? If we have a very small number of runs, then the Monte Carlo simulation result may not mean much, so we should have a bigger number of runs, but this will increase simulation time.

Am I right in thinking that 370 runs is a good compromise between simulation time and accuracy?

Thanks,

YH
