If you look at the curve in the battens you can see he has it flat at the top but still full at the bottom. As you depower, watch the top battens. You want to see the top flatten. I would start with the rotation at the side stay. The top should flatten pretty quickly as downhaul and main are tightened because the mast is bendy on the narrow axis/unsupported at the top. Then bring the rotation back. When you see the top of the sail start to get fuller you have rotated too far back. The top of the mast is straightening out because it is stiff on the wide axis. You would like the sail to be flat and rotate back a lot but our mast does not support this.
