I've not noted a "step change" in my CNX80. The changes in sensitivity are
supposed to be gradual, and at the FAF I believe the "scaling" goes to
angular, to mimic an ILS. But maybe I've just missed it.

As I understand it, it first ramps down to 0.3 from 1.0 starting at 2
miles from the LPV FAF, then it does a continuous angular "ramp down"
from the FAF to the runway so it will be ILS-like close in. Have you
noted that doing small incremental "stepping" on an LPV IAP during final
approach?

Well, I'm hand-flying most of the approaches, and the CDI is generally
centered prior to the FAF, so I wouldn't note a sudden change in
sensitivity on the final segment.

I do, of course, note the change going from enroute to terminal mode, and
from terminal to approach mode if I have any CDI deflection.
