Both segments took over a week to post, probably US's fault initially, but such that they both posted post-integration and now after re-integration only one of them is actually visible in the activity report. But I can calculate from my summed PQMs that they remain different.
I hate to say it but... your mileage may vary

Hmmmm ... i may be over-extrapolating here, but: pre-3/3, did OP elite members get the 500-mile minimum credit on US flights, even if the actual miles were lower? (MP members got actual, even elites ... I spent a LOT of time confirming the old MP rules on this -- "US determines miles awarded".)
I've done literally hundreds of connecting flights between SBY and PHL on US over the years ... if that's the case, as a PMUA 1K I'd wager that my Lifetime miles are >50k lower than they would have been if I were a PMCO Platinum.
