I believe the SCI counts an attendee for every day that he/she attends or pays to attend. Attend four days and you will be counted four times as an attendee. Not sure wether or not they count the exhibitors as part of their attendees, that would be interesting to know. Here are some numbers that I could find from searching AH...
