That tracks with bench measurements gentlemen, I'm seeing full rated V at 1000 M Ohms load and 1 kV DC, but not at 10,000 M Ohms.
Now on to the next measurement which requires an electrostatic Voltmeter.

Ah! Excellent! Down to 1uA with 10uA being
comfortably on the curve, and that is a 1/2Watt Zener which is
the most common kind I see.
I notice the Zener (or Avalanche) voltage
increases linearly up to about 1mA, then increases at a higher
rate, no doubt due to extrinsic series resistance in the bulk
material of the chip. I wonder why they spec operation in the
tables at 5mA?
