As a car owner and I also work a full time job, mid week races are hard to make. Also with USAC going out of town the next day, a lot of teams don't want the risk of a car being destroyed. These two things along with Ohio Speedweek, is the reason for the low car count. Needed to be on a weekend day, and a week where USAC teams aren't traveling. Some day promoters will make sure to check other schedules.
