I've seen this before. I like to cook dark meat parts to 180 plus. Not the best solution, but it works for me.
Another trick I like when cooking chicken leg quarters. Slice the joint between leg and thigh to allow the juices/fat to escape during cooking. All common sense tells you this is a bad thing to do, but it works great.
