To properly test the tolerance of the zero ohm resistors you need to build
R-2R DAC using 0.01% Zero-Ohm resistors. Characterize the ladder then
substitute the unknown resistor with the MSB resistor in the ladder. You can
use a 16C7x to control the DAC and read the result. Make sure the
temperature gradient across the ladder is < a few degrees.

You will probably find that they actually do meet tolerance (unless they are
installed backwards).

I prefer to look for the ones with the black-black-white bands. You get a
lot
more zeros for your money. But you're right, they never seem to meet the
tolerance.
