Agreed on Excel not being a suitable tool for MC; that's one of the many things that pushed me in the direction of building ProjectiFi. Within ProjectiFi, I'm sure there are some things that could be done to speed them up further (e.g. offloading them to a backend where they can run faster), but there could also be some trade-offs with that -- for one, it would violate the "everything stays client-side by default" principle mentioned in another comment.

I guess it's just me who hasn't yet seen any serious mc simulation running on a client I guess :/
The way I see this done whenever it runs fast is using c/c++/java. Another important thing with statistics is the mathematical validity of your results, regardless of whether they look right. For validation, most literature I come across uses c/c++/r.
