Sampling has proven extremely useful. Pi can be approximated with it as were nuclear bombs designed using statistical methods. Flame graphs based on stack samples are used to optimize servers. Government does planning with it. Management does its thing by wandering around. It usually does not take many data points for an actionable insight and most actions then will invalidate small details in old data anyhow. Better to start every round with fresh eyes.
