First off leave the bike that shifts well alone before you bullox it up too LOL.
Tell us a bit about the poorly shifting bike? what brand model drive? tons of miles? how is the chain? if the hanger was bent when you picked it up it is posssible that the derailleur is bent too, but not enough that you can see it.
you can change the shifter from friction to index? so it has thumbshifters? I somewhat suspect a shifter or cable binding issue.
BTW working upsidedown should not have bearing on this measurement but is hard on the knees
