Table schema:
CREATE TABLE table_name_73 (average VARCHAR, attendance VARCHAR, sellouts VARCHAR, season VARCHAR)

Question: What is the full amount of averages when the sellouts are less than 14, the season is 2011-12, and attendance is less than 162,474?
SQL: SELECT COUNT(average) FROM table_name_73 WHERE sellouts < 14 AND season = "2011-12" AND attendance < 162 OFFSET 474
