I personally get a feeling that 47% mastery is the best within my soul. I just get a deep feeling and at around that point of mastery I release a long fart of satisfaction. A feeling fart. And then peace washes over me and I become all powerful. I understand the universe and there is a calm in my mind. 47% mastery just does it for me spiritually. I don't care about your hard work and theory crafting babs. I have a deep spiritual awakening at 47% mastery.
