What I meant was that a UA 1K for multiple years, I never had issues getting partner miles credited. I can estimate that it was perhaps 1x/year and I do a lot of flying on *A.

But since the 3/3 merger date, things changed dramatically for me.

I can't speak for what it was like for CO customers prior to 3/3, but it certainly seems that UA elites had a sharp decline in this area since the merger.
