Birdwell, nice diagram, but too complex for me. I've been using new numbers, based on 12 increments, and for the most part, it seems to be working. My confidence was completely gone before my last round. There's a bit more room for error with 12 increments, as the gap between increments is longer, but with more practice, it'll get better.
Good luck fellow avatar increment players. We'll all adjust in time.
