In recent years it tends to be a ton. Off the top of my head, Ave won for Propeller and to a lesser extent his stuff in Boys of Summer. BA won for Jump off a Building and his euro contest stuff that year. Koston won for Mouse and winning Tampa, Arto won for Sorry, Apples for Really Sorry, Carroll for FTC-Finally and Goldfish, Ishod won for his Fourstar part in Philly, his Sabotage 3 part and most importantly his Chronicles 2 part, MJ for his Fully Flared Part. Those are the only SOTY runs I vividly remember. I know the main parts for other ones, but can't pinpoint all the parts they dropped.
