What happens if you put two components in parallel — does the effective tolerance increase or decrease?</p> <p>I had some very wrong assumptions about the answers to these two questions and am glad I looked deeper in to the topic. Some very suprising, yet satisfying and reassuring insights into error boundaries and propagation lie ahead. So buckle up and get ready for some math!
