I've done some looking, but what happens when there is no nonstop routing, e.g. ADL-CNS (I have to use CNS because for some reason PX is not operating the 763 to POM Saturday Nov 8, but has two flights to POM from CNS.) It now looks like SFO-HKG-ADL (using CX all the way) x ADL-SYD-CNS x CNS-SYD-SFO (using QF all the way.) CNS-POM-GUR-POM-CNS nested using PX. Even calculating SYD in the mix for connection purposes, it's still under MPM, so it's not a major worry.
