The order of the list for each category Flight Instruction and Ground Instruction defines the order in which the Instructor rate will be used during check in.
Example: If it says Aircraft, Instructor, Group then during checkin, if Aircraft has a rate specified for Instructor, it will be used. If none, then it will check if the instructor has a rate specified. Then Group. Then if none, it will just use the first instructor rate.
