CREATE TABLE table_35067 ("Driver" TEXT, "Front row starts" FLOAT, "Pole positions" FLOAT, "Entries" FLOAT, "Percentage" TEXT)

What's the average front row starts for drivers with less than 68 pole positions and entries lower than 52?
SELECT AVG("Front row starts") FROM table_35067 WHERE "Pole positions" < '68' AND "Entries" < '52'
SELECT AVG("Front row starts") FROM "table_35067" WHERE "Entries" < '52' AND "Pole positions" < '68'
