Anyone sat down and crunched the numbers to determine the odds of success for rolls? I know it changes things with boost dice, skill dice, setback, and challange. But it would be nice to know.

I could do it myself but I had a hard enough time creating a spreadsheet to simulate dice rolls in SW:EotE

Let me Google that for you…

and from reading the thread on that link, twice.

The answer to my orginal post would be, yes, but they just used a dice simulator to get a sampling.
