#1241, Is an unusual description of trim - stick force and aircraft control.
Most professional pilots already have an adequate understanding of this and the various relationships, including speed - thrust, and configuration.

The primary objective of control is to achieve the required flightpath (not where the trim is going), using stick input to change pitch. When a stable condition is achieved, including speed, then trim can be applied to reduce stick force.

Differences in views about the ability to identify a trim runaway, perceive, comprehend, relate, and choose action (checklist) appear to be fundamental to the current delay in return to service.
