Great work. Also, I highly recommend the video you did on back-testing. It is some of the best 38 1/2 minutes I will spend in research! As a quality engineer back in 1983 I learned about the "law of large numbers" in statistical sampling. We predicted manufacturing "defects per million" via Cpk (capability), but if our sample size was too small, or variation too large, we would have "inference error", or, as you so gracefully stated in your video, the "law of small numbers". Very informative, educational, and, you have a wry sense of humor which I enjoy. Thank you. Don.
