I'm not saying anything one way or another about this because I
haven't followed the discussion that close, but there is something to
keep in mind.
Transformers and matching systems with loss are not symmetrical when
reversed. In other words, a perfect SWR 9:1 step down transformer is
not 1:9 when used to step impedance up (between the same impedance
ratios) if it has loss. This creates a real problem when measuring
performance and loss with back-to-back identical transformers or
matching systems with loss.
We should never assume a RF transformer or matching network is
symmetrical, unless we know for sure it is nearly lossless.73, Tom
