Humidified air is a very nice, slow discharge path; either a humidifier
or a good "huff" from the mouth works well.

This is a classic test problem. I've seen this several times. For
this setup, there is no place for the charge to dissipate between
zaps. So, how to discharge between zaps? The easy answer is to
briefly connect a strap from apparatus to ground. But that casues
lots of problems, including false "failures".
The reason? The discharge created when using a zero Ohm strap is
uncontrolled. If you remove the "bleed" resistor, then the discharge
is not bleeding slowly, it becomes another form of an ESD discharge.
The problem is that the waveform will not be representative of the
human-body-model. ...
