Interesting. And, no, I wasn’t there, either. I was 6 years old at the time

The 80/80 rule was/is applied for auditing manufacturing as, according to
management, 'good enough for government work.' They figured the risk of
getting caught was sufficiently low enough to continue shipping.
Initial testing has no allowance for exceeding the requirements.

Yes, 20% is an over-estimate for committees with more than five members.
My view (and I think it might even begin to be believed) is that it can
be accepted that standards should not allow, or even encourage, the
shipment of non-compliant product. The manufacturer alone must decide
how to cope

That's the 80/20 rule, which is an entirely different thing. It applies to
standards committees; 20 % of members do all the work and 80 % just accept the
results.

If my memory serves me right, as I recall, the 80/80 rule was in at least one
of the VDE standards regarding radiated emissions. I can’t recall the number or
name. This is going back to the late ‘70s or so.
