Little humor:

I am a big fan of plastigauge, and checking everything twice.

Did the usually trick on one crank that have been turned "20/10"
Checking everything, the crank mains were indeed 0.020" undersized.
All the rod journal were 0.010" undersized, except ONE that was at
0.020" and didn't touch my plastigauge.  Took a bit to believe
my eyes...  I had dealt with the machine shop before, and I know
it was a fluke... just how it happened was the mystery? (lunch
break?)

Ya, measure twice. ;-)
