This write up is a nice start. It does not point out that adjusting the chainlength, upper tension spring and lower tension spring is iterative, with the variation from the front chainwheels coming in to boot. They all affect each other and you need to fiddle. Properly adjusting one of these derailleurs from scratch takes a good 45 minutes if not more. It is also likely that your existing adjustment is less than optimum if you haven't gone through the whole exercise. On a limited range freewheel, when you get it right, these derailleurs shift wonderfully.
