Once, in the ancient times of the old forums there was a really nice article covering al that *shudder* math. Does someone know where else can I find it?

I wrote a script that figured it all out. I'll see if I can dig it up and generate some graphs.

IIRC, some of the steps have wacky curves to them, but they all average pretty closely to their step number.

"Wacky" = not all of the steps had similar curves

I got that, and I think they do (except single-die ones).

I found some pdf with that kind of statistical analysis, but it seems it was off in some places (I can't say, not my field). I remember that article was impressive enough to make me read it thoroughly, despite the math...

There's been a question like this on RPG.SE: , perhaps it will help you. Alas the link in the top voted answer links back to the now missing article from the old home page, but there's quite some explanation going on in the other answers.

I can also recommend http://anydice.com/ for calculating odds.

I wrote that article from the old site (for the old step system). I need to dig it up and make it available online.
