The plan of action is to start with replacing the balance staff, then pallet fork, escape wheel, rest of the gear train.
Pallet fork and balance staff replacement usually get me enough amplitude to barely reach tolerance...

Are these parts visibly worn or "off" in any way that you can see? Is there some inherent defect that takes awhile to manifest in a part but the tolerances are so small that they are invisible? Or is it more a problem of stacking tolerances across the parts where certain assemblies will be doomed from the start due to the individual tolerances adding up to something that will fail or never work quite right?

That could help explain why only some movements are affected.
