Can someone link or list the UG priority (as shown on CO.com) for BF flights?

I am flying today and the results don't make much sense.

I booked 2 tickets together online for my (Silver) wife and I (PPlat, was Plat when booked >3 months ago). After the UA legs upgraded I had the PNR split. Last week. SWU's have been wait listed since booking for this leg (HNL IAH) >3 months.

I checked my wife in online first, then me. She appeared #1 and me #2. Now ~18 hrs later I am #3 and someone else is #2. They can't have higher status than me. They also can't have either higher fare or earlier wait list than me without also having it over her. Since they just appeared on the list they also can't have checked in between us. Based on what I know this just doesn't add up.
