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 ###
TABLE: CREATE TABLE table_46174 ( "Rank" real, "Team" text, "Played" real, "Loss" real, "Last 5" text, "Streak" text, "PF per game" real, "PA per game" real, "PD per game" real, "Winning %" text )

### Question ###
Which PD per game has a Rank smaller than 4, a Winning % of 78.6%, a Streak of w1, and a PA per game smaller than 81.5?

### Accurate SQL ###

SELECT MIN("PD per game") FROM table_46174 WHERE "Rank" < '4' AND "Winning %" = '78.6%' AND "Streak" = 'w1' AND "PA per game" < '81.5'
