	UPDATING INSTRUCTIONS
	DO NOT TOUCH THIS DOCUMENT
	TO UPDATE THE STANDARDS GO THE XML FOLDER, IN THE FOLDER ARE XML DOCUMENTS THAT CONTAIN THE DIFFERENT STANDARDS FOR EACH AGE GROUP
	FOR EXAMPLE: male19.XML CONTAINS THE STANDARDS FOR MALES FROM 19 TO 23
	WITHIN THE XML DOCUMENTS CU STANDS FOR CURL-UPS, PU FOR PUSH-UPS, THE FIRST SET OF STANDARDS IS FOR OUTSTANDING HIGH, AND PROCEEDS DOWN
	THE LIST OF CATEGORIES FOR EACH STANDARD ENDING WITH PROBATIONARY
