CREATE TABLE table_31197 ("Skip  ( Club ) " TEXT, "W" FLOAT, "L" FLOAT, "PF" FLOAT, "PA" FLOAT, "Ends Won" FLOAT, "Ends Lost" FLOAT, "Blank Ends" FLOAT, "Stolen Ends" FLOAT)

When 36 is the amount of ends won how many sets of pf's are there?
SELECT COUNT("PF") FROM table_31197 WHERE "Ends Won" = '36'
SELECT COUNT("PF") FROM "table_31197" WHERE "Ends Won" = '36'
