    Write a function to analyze a patient's medical record identifier and determine how many characters in the ID match their corresponding positions in the standard hospital alphabetical validation sequence (A=1, B=2, etc.), regardless of letter case. This validation check helps prevent documentation errors during patient readmission processing and ensures data integrity across the hospital's record management system.
