    In a hospital's risk assessment system, develop a function that calculates a patient's current risk score based on the nth historical medical event in their sequential health pattern, where each new risk score is determined by the frequency of critical events in previous positions following the Newman-Conway relationship. The risk scoring system starts with initial values of 1,1 and each subsequent score is determined by the sum of the scores at positions P(P(n-1)) and P(n-P(n-1)), where P(n) represents the risk score at position n.
