    Design a function for the credit assessment system that evaluates if a customer's credit pattern identifier is one less than twice its reversed value, which serves as a key indicator in the automated risk scoring model. The function should take a single positive integer representing the customer's credit pattern identifier and determine if this mathematical relationship holds true.
