I think there is an important distinction between accuracy and precision in engineering. I'm having flashbacks of sitting in class when the professor was going over this stuff. I honestly always found it some of the most boring topics in the curriculum.
One of my physics profs had a story about this. He needed two resistors to be very similar in performance for a circuit he was making, so he asked for a couple of the super-high-quality ones.
His advisor said "fuck that, get the 1% bin, they'll be bimodal at 1% above and below rating, sort em and find two that match to the degree you need"
That's kind of analogous; do you need to try to hit a particular value (accuracy) or do you need things in a consistent relation to one another (precision)?
