You exhibit "Instant Hip Acceleration" when you do "sustain the lag" ("lag"-controlled pivot through the hands).

You exhibit "Instant Hip Over-Acceleration" when you do "Instant Hip Acceleration" (pivot-controlled "throwaway").

There is nothing wrong with "throwaway", as long as it occurs beyond impact, like what "sustain-the-lag" does. The only problem is that it's quite difficult to make it happen beyond impact and time it precisely and thus demands more practice and is less reliable under pressure.

I'll buy that. . . but let me ask you . . . at what INSTANT does instant hip acceleration begin?
