May I ask what the 3 states are that correctly model Fisher's intentions?It isn't necessary. Fisher complicates things because he has the right idea, but expresses it through a cluttered mind.
There are only 3 states that you need to capture, and I score them as 1, 2 and 3. The correlation with his idea is almost perfect.
People get hung up on the scoring and the detail. Understand the concept.
Thanks.
