"If you record 100,000 rolls and you are off by more than a standard deviation, you know something is wrong."

The rest of your post is useful but you should stay away from the technical details. You would not know that something is wrong but instead have evidence for it and a single standard deviation is nothing special at all. Being off by more than a standard deviation should happen close to 32% of the time.
