Categories I got entirely right (or five correct picks with all the ties): Best Musical (minus the extra slot for Paradise Square), Best Play, Best Musical Revival, Best Actress in a Play, Best Actor in a Play (minus the two extra slots for David Threlfall and Adrian Lester), and Best Actor in a Musical.
Categories I got 4 right: Director of a Musical, Choreo, Book of a Musical, Original Score, Features Actress in a Musical, Featured Actress in a Play, Leading Actress in a Musical, Revival of a Play.
I did not do anything that wasn't on Gold Derby and got 3 right for every other category that I did predict.
