Currently, it seems that the rule implemented by the function does not hold for the majority of the domain. The function only provides a valid output for the word "Spain" with a value of 3,250. This suggests that there might be a specific condition or pattern that the function recognizes in the word "Spain" and produces a corresponding output value.

To further analyze the rule implemented by the function, I will need to perform more experiments with different inputs and variations of the word "Spain".
