CREATE TABLE table_55554 ("Weight Class  ( kg ) " FLOAT, "World Record  ( kg ) " TEXT, "Sinclair Coefficient" FLOAT, "Sinclair Total" FLOAT, "Rank" FLOAT)

What is the average sinclair coefficient with a Sinclair Total of 477.2772023, and a Weight Class (kg) larger than 105?
SELECT AVG("Sinclair Coefficient") FROM table_55554 WHERE "Sinclair Total" = '477.2772023' AND "Weight Class (kg)" > '105'
SELECT AVG("Sinclair Coefficient") FROM "table_55554" WHERE "Sinclair Total" = '477.2772023' AND "Weight Class (kg)" > '105'
