I didn't want to jump in on this one, but now your post has been here for two weeks without a single response. I can just as well give and answer and hope for the more knowledgeable guys to correct me.
Without any warranty, no assumed liability and everything else you can think up for a disclaimer: Here is a formula I made up:
