I've heard this story ever since I was a kid, but never been able to find a credible source. I'm compelled to believe it's no more than a story, at this point.
It was in an audiobook narrated by Pat Morita that I heard it.
The context was auto transmissions --- it was found that one source of premature failures was when all parts in a transmission were at the extreme of too small or too large --- on average, the large/small would balance out, but when it didn't that was when there were early (and catastrophic) failures.
