Yep. Picked 32640 because the last two values are, from my understanding, inconsistently handled by transmitters due to how far from norm they are.
If you're doing 32000ft/min you're clearly going *muuuuch* too fast, either up or down, implausibly so.
Unless you're in a jet fighter aircraft in which case showing up correctly on flightradar24 is not your biggest worry.
