Malcolm,
Since part of the operation is unloaded (before break-out) and part of
it it loaded (after break-out), the match may have to be a compromise,
although intuition tells me that the loaded match may be more
important, but I don't trust my intuition too much either. But these
changing conditions may be what makes the whole thing somewhat
non-critical, if it is indeed non-critical. The experiments by Lou
Balint in which he used various types of secondaries, and tuned
them with an external parallel cap seemed to show a basic
non-criticalness of the matching, i.e. there doesn't seem to be
any *peak* in performance caused by an excellent match. But
none of this is conclusive, more work is needed.
