Howdy,
About the only thing I'll add is think about the last posse shooting that stage. Tired, maybe hot, maybe ready to be done.
Keep the target orders simple and straightforward. If you're going to do some fancy stuff, make it simple and easy. If it's a reload, do just one. Move them around on the line, but make the targets easy to track.
Good for you, stepping up and sharing the load. Adios,
