These 3 pages alone tell the real AT HF interface story
After having flown, tested, or evaluated all four big jet manufacturer's types in some of the most stressful conditions or configurations experienced within the flight envelope, and some times in ranges beyond the edges, ...for nearly four decades, ... these three pages of comments alone, addressing this simple question, ...provide a "telling story" regarding the suitability and characteristics of the modern Bus non-moving throttle design. In that regard, these three pages of comments alone are all that's needed, to begin to draw conclusions about the real story, of both the suitability, strengths, and weakness of that particular pilot-aircraft thrust/speed interface. It should be as simple as either AT ON, or alternately push forward for more thrust, and pull back for less, as needed, ...if the AT isn't doing what you expect or need. Even the issue of electing to disconnect the AT, or not, is secondary.
