Question: What is the percentage of Russian players who have a height of under 200 inch?
SQL: SELECT CAST(COUNT(CASE WHEN T1.height_in_cm < 200 AND T2.nation = 'Russia' THEN T2.ELITEID ELSE NULL END) AS REAL) * 100 / COUNT(T2.ELITEID) FROM height_info AS T1 INNER JOIN PlayerInfo AS T2 ON T1.height_id = T2.height
