The trouble with Chevy is they would order the tooling and test

We larded the test station for their 1970's analog ABS controller with
jumpers so they could change the test parameters themselves. While I
enjoyed flying first-class I didn't at all like Flint MI. For some
reason there weren't many passengers on those flights.

GM's project engineer was a Ph.D. from India with absolutely no
practical hands-on experience. He wanted the ramp-down curve of wheel
sensor speed accurate to 8 decimal places because that's what his
calculator gave him. No one had taught him that resistors have
tolerances.

Today, .01% are easy to get.
LaSer trimmed can be even closer.

You can buy 'as marked' but they are only that value at a specific
temperature and they aren't cheap. Considering that the first standard
was 50%, .01% is a 5000% improvement. I've bought reels of .o1% on Ebay
for well under one cent per part.
