Remember, it is all about dollars. As they said during Watergate, "Follow the money." Always go with the money.
Any ticket sold for any amount of money counts toward the percentage so in theory a show could reach 100+% and yet not sell one ticket at full price.
Also, would you like 102% of an 1100 seat theatre or 100% of a 1900 seat theatre? I myself, prefer the latter.
