Calculate the percentage of users with a high number of fans who were elite in 2011.
users with a high number of fans refers to user_fans = 'High'; 2011 refers to actual_year = 2011; Calculation = DIVIDE(Elite.user_id where user_fans = 'High' AND actual_year = 2011, Elite.user_id where actual_year = 2011) * 100
SELECT CAST(SUM(CASE WHEN T3.user_fans = 'High' THEN 1 ELSE 0 END) AS REAL) * 100 / COUNT(T3.user_fans) FROM Years AS T1 INNER JOIN Elite AS T2 ON T1.year_id = T2.year_id INNER JOIN Users AS T3 ON T2.user_id = T3.user_id WHERE T1.actual_year = 2011
