take these "holes" caused by factory robbery into
account when they specify their parts... I never
did, but perhaps the production guys would have
liked me better if I had?
You think you are using a 1K nominal part, +/-5%,
but in reality, your part is really:
[1.05K|0.95K] +/-2.5% of 1K
You thought you bought a one humped dromedary camel,
but Amil the camel dealer came rolling up to your
camp with a two humped bactrain camel, and none of
your saddles will fit.
It puts a completely different spin on a Monte Carlo
analysis on part tolerances.
No wonder HP only used 1% or better parts.
