Yeah he is constantly weighing, and using a high end moisture meter. He has some formula in his head of starting weight and moisture content, versus how much cooking, and at what temp, and he keeps calculating as he goes. Like I said, he's a mad scientist kinda guy. But he has some initial cracking, and it's like he gets it under control pretty quickly.
I don't even ask him questions anymore, his answers just go ZOOM right over my head, and I'd like to think I have a pretty good concept of wood, moisture, and drying. :-))
