I also think you are doing something wrong. I ran 5600 for a few years, and it was only finnicky when the cables wore out. After replacement, it was set and forget for a couple of years.
I agree there is something weird going on if your 10 speed keeps going out of whack. The only things that I can think of that should affect the tuning are cable friction (either within the housing or under-BB shell cable guide), cable housing compression, or something gunked up internally in the shifter. I guess there could be other problems if you have an old or defective rear derailer where the return spring was weak or there is too much play in the pivot points.
