Clearly I'm missing something, because I still don't understand.  Let's take
a simple example of a move is on the 3rd line and has a gamma value of 1.75.
What is the equation or sequence of discrete values that I can take the
derivative of?

Doing conditional probabilities based on "move is on 3rd line" and "move is
selected" (AKA pure training data) seems to yield a fixed value rather than
something approximating a normal distribution.
