OTOH, worst case is very pessimistic, except for circuits with very low
parts count. 100 Monte Carlo runs give a good guide to the sensitivity
of the circuit performance against component values. If the values used
for each run are logged, it's possible to see which parts are
responsible for any suspiciously larger excursion of performance.
