Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###

### Question ###
What is the total matches in 2002 where points won is larger than 1.5 and the points % is smaller than 50?

SELECT MAX(total_matches) FROM table_name_4 WHERE points_won > 1.5 AND year = "2002" AND points__percentage < 50
