I've rushed multiple times and had different seats each time. But they all were EXTREMELY partial view. I wouldn't recommend them if you haven't seen the show. You miss a lot. I won the lotto though, and surprisingly those seats were not partial view at all and were in orchestra row R.
I don't think they're selling rush later in the day anymore, because I've tried between 12-6 quite a few days over the last few weeks with no luck. Between the lotto and rush, I'd say they allocate a set number now and that's it. The $69 tickets aren't bad, especially because closer to curtain they sell the front mezz at that price.
