Learned engineers, leaving the unraveling of part 25 to you may I add a word of caution from the pilots union.
Having flown one of those test points once, ...and only once, listen to the test pilot and aircraft; they can talk to you and add to the picture formed by regulations, design documents, and test plans.
As I recall, flying the manoeuvre point was very difficult, particularly to hit the test point by diving and to manoeuvre within height and speed boundaries; there were additional issues with very high manual control forces.
The test point was exceeded by a tiny weeny bit, M.005.
At the debrief the engineers bounced around; aerodynamics and structures with expressions of surprise and relief that everything held together!
