I think the flow chart in the booklet accompanying the TRT 2d ed. is incorrect. I cross referenced to the flow chart in Volume 1 of Lardy's Retriever Journal articles and the flow chart reflects what is shown in the dvds.
In the big scheme of things I don't know that it matters that much. There is probably only one or two days separating the two drills. With my last two dogs Hank and Rowdy (by Pirate), their casting was so good that I didn't get a chance to do indirect pressure at that point in their progress.
