    Write a function that analyzes a bus route identifier string to determine how many of its characters align with optimal timing slots, where a character matches its natural alphabetical position (case insensitive). This alignment indicates schedule efficiency, where 'A' in position 1, 'B' in position 2, etc., represents ideal timing windows for the route's operation.
