The issue is that NY Democrats have been proven incapable of holding down anything less than Biden +12 or so, especially given their history in the Syracuse seat. So you need to draw spaghetti to make it happen.
Well, regardless of the answer to the question in my post above, I went ahead and made one more county split, which brought the Midstate districts to Biden +10 and Biden +11, while the "Stefanik" seat is Biden +5. The Binghamton/Ithaca/Syracuse seat is Biden +18.
There's no reason the NY Dems can't have a highly functional map that also is not horrifically erose, and I feel it would wise of them to insulate against court challenges, plus defang any organizational outrage attempts among the state GOP against maps that obviously look gerrymandered to the average citizen's eye.
