CREATE TABLE table_70957 ("Parties and voter communities" TEXT, "% 2006" FLOAT, "seats 2006" FLOAT, "% 2001" FLOAT, "seats 2001" FLOAT)

When seats for 2001 is greater than 15 and % 2001 is greater than 100, what is the % 2006?
SELECT AVG("% 2006") FROM table_70957 WHERE "seats 2001" > '15' AND "% 2001" > '100'
SELECT AVG("% 2006") FROM "table_70957" WHERE "% 2001" > '100' AND "seats 2001" > '15'
