    【Question】
    What is the average star with highest percentage for episodes that have received award? received award refers to result = 'Winner'; the highest percentage refers to max(percent); average star = divide(sum(stars), count(episode_id))

    【Evidence】
    received award refers to result = 'Winner'; the highest percentage refers to max(percent); average star = divide(sum(stars), count(episode_id))

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT T2.person_id FROM Vote AS T1 INNER JOIN Award AS T2 ON T1.episode_id = T2.episode_id ORDER BY T1.percent DESC LIMIT 1
