(M0.8 to M1.2 takes 8 seconds for the A, 16 seconds for B and the C takes.... 43 seconds.)
those numbers are incorrect.
the numbers you have provided are how much they missed the mark on the
Transonic acceleration KPP by. I apologise but I cannot find what the KPP called for.
8s from 0.8 to 1.2 would be insane, and I suspect most would think that 43 seconds for 0.8 to 1.2 is “okay”.
