I seem to have gotten my rear derailer straightened out.
I went into it thinking I totally knew what I was doing, since I was pretty comfortable with the front derailer by the time I went to bed last night. But it wasn't cooperating. I was only messing with the cable tension knob. And... it was not very responsive.
Then I watched a couple videos on the rear derailer, and realized there's a cable tension knob right on the derailer. Which, for obvious reasons (friction), is *much* more responsive.
Then I sat on my floor for half an hour, with my bike upside down, running back and forth through the rear gears, fiddling with the tension, to balance out the smoothness of up-shifts and down-shifts as much as possible. Not because that amount of time was remotely appropriate, but because it was fun.
I still don't understand how people cope with the lack of lock nuts on these things.

and the cables have finger level adjustments on both ends of each cable; i've had to tweak on the fly.
AND if you count the actual cable clamp, that's two more.
when i upgraded my shifters, the instructions came with "the procedure"... basically you first have to reset the physical ranges, adjust gross physical cable length, and then tune the tension levels.
the pros can do it in under 20 minutes. takes make 2-3 times longer as i rarely have to do it. after new cables break in, very few adjustments are required, even phyiscal ranges.
keep it clean, and lubed, esp the chain, and bob's your uncle.
