your mostly correct re explaination for min and max acceleration altitude.
except max acceleration is limited by 5 or 10 minute thrust reduction to end of THIRD segment (accleration segement).
However at high altitude airports (Bogota) with high obstacles, airbus software gives max acceleraion altitude lower than the minimum acceleration altitude......
software gets confused and gives an output of:
Min accel height: *****
Max accel height: *****
Trying sticking that into to your onboard systems
