Table schema:
CREATE TABLE table_name_31 (mrc_championships INTEGER, solo VARCHAR, pct VARCHAR, co_champions VARCHAR)

Question: What is the average value of MRC Championships with more than 0.685 PCT., more than 1 for co-champions, and less than 5 solo?
SQL: SELECT AVG(mrc_championships) FROM table_name_31 WHERE pct > 0.685 AND co_champions > 1 AND solo < 5
