Another spec I have seen is 8kV 200pF and 2000 ohms. The problem is the
voltage because Wc ~= U^2. There are also issues with C. Anybody who did
some sort of work on radio knows that 100pF is bogus for the human body.

8kV/200pF model = 10mJ

It all goes back to whether the parts are specced for
factory/technician/adjustment type ESD environment or direct exposure to
the elements, where you have no control at all. You can also get exposure
to Mr. David van Horn who can shuffle the plastic carpet up to your device
in an exhibit and touch the keypad.
