Table schema:
CREATE TABLE table_name_41 (_number_of_home_games INTEGER, average_attendance VARCHAR, year VARCHAR, canada___usa_rank VARCHAR)

Question: Before 2012, what was the greatest # of Home Games with a Canada - USA Rank of 52nd, and an Average Attendance less than 992?
SQL: SELECT MAX(_number_of_home_games) FROM table_name_41 WHERE year < 2012 AND canada___usa_rank = "52nd" AND average_attendance < 992
