ALTN and DCT is how the discussion started, yes.
On top of that, the poster has a technical description that explains different surface deflections needed to achieve 5°/sec (clearly NORMAL law) for the different approach flap settings. Now, if Normal Law for F4 needed to provide almost double the deflection compared to F3, guess it must be the same the pilot under ALTN or DCT. To achieve the same response with F4, more deflection
of the stick, this time? And for the same stick command, the A/C would feel half-responsive compared to F3.
Speculation.
