No doubt my feedline is wrong for a lot of frequencies, made more clear by
the fact that there are a few frequencies where my LDG autotuner can't
find a match.

However, how much does the feedline length matter IF the autotuner is able
to find a good match point?

Some impedances are outside the matching range and some
impedances are barely inside the matching range. Some
of the latter may not be a "good" match point. I model
my antenna systems to get a ballpark idea of what
impedance I am up against and use an antenna analyzer
to fine tune the system.
