Oh you are a girl after my own heart! I have done the same...gone down 100's of rows to fix a twisted stitch! LOL! I thought I all alone in my boat of OCD!
But I feel very satisfied with the outcome, as you do! On this particular project I mentioned...I don't know why...but I had to do this deep teardown to fix a single stitch more than once.
Sometimes it was a twisted stitch, sometimes it was a stitch that had been knit with the stitch below. Heaven help me.
