Uh, “much much faster” is 1st derivative. “Getting faster” is second derivative.

While you are tripping over semantics ponder on this:

Is it 'getting faster' if 'much much faster' is faster than 'much faster'?

I don't have much patience for linguistic prescriptivists. If you are 'correcting' other people's sentences you understood exactly what they mean.
