It certainly would have helped if the "readme" had included an explanation; however, this gives the player a chance to experiment and see what it does.
I know what it does for the PLAYER ... I don't know what it does to the AI controlled CIVS. IT really matters very little whether or not I know what it does for the AI. If it increases MY game enjoyment, I would most likely play with accelerated production; if not, I won't. Since its an option, it's my choice, not something FIRAXIS decided for me.
