Haven't looked into stopovers yet. However, all of those should be around 180/SC if you use minimal points + cash and not including points you get back from the flights.
Thanks for your original post. I did some calculations and have shown them in the table below. You are right, it averages out to about 180/SC with cash or 340 using points only. Of course you will, as you point out, get points back depending on your current status.
