# There are nine beasts in a memory and there are nine kinds of harvest beasts with equal chance. Thus, the expected value is one beast per memory and the income is the sum of their value.
# However, only five is worth selling, the two Primal C beasts are worthless, Primal Rhex Matriach (synth map) and Vivid Abberach (guardian map) we run ourselves.

# It's near impossible to calculate the expected value for guardian maps so I am skipping it. It's 20-40c at most anyways.
# Finally, the cost:
