That's about the right spot. An important thing to check is the condition of the leather brake pad. If the leather has gone dry and hard, or worn, or has ANY kind of lube contamination it won't have the same hold on the breaker plate, likewise if the edge of the plate has any rust or roughness, it will bind on the brake pad and give you bad timing.
