I love the Baney 1k ladder method. Works like a charm and you don't burn up valuable barrel life finding the sweet node.
Also, for those planning on using a video camera. 1) Check your battery life. 2) Many vids and their batteries don't work well during cold weather. My favorite time of year to develop loads is winter time, when my barrel temp stays much cooler and I don't have to wait much or at all between shots.
Ask me how I know about video camera battery life

Nothing like shooting a ladder, getting home and watching a screen go black.
