I was speaking with a customer that would like the ability for standard deviations in the rules engine.  Can you provide some context into if this is something we are working as part of roadmap? 
Standard Deviations would be AMAZING! With those available, you could tell if a change was significant or not! Thanks for posting this!!!
Formula builder in Rules / Report builder is on the roadmap but Standard deviation is not part of the first cut. Thanks for putting it here, I will see if we can add SD function to the first cut.
