For now I've updated the Idle System Overview with a graph that assumes the AWS contributes 750 RPM to idle. With that graph, hopefully people can diagnose, based off of their idle, what components aren't functional. The main goal is to provide a better understanding of the idle system, at a glance, than scanning the FSM carefully and posting a new thread. Being community maintained, if you have improvements, go ahead and fix/improve the reference. If there's anything this thread proves, it's that these references are always made better with community input.
