On the second disk of Lardy's TRT, Lardy introduces indirect pressure utilizing the here "nick" sit for lack of effort during simple cast drills. In his example the dog goes to the wrong pile and presents Lardy an opportunity for introducing and utilizing indirect pressure. I get that concept, but he also mentions indirect pressure can be used for shopping the bumpers, lollygagging over the pile etc. But he doesn't go in to how to apply it when those situations occur when the dog is on the pile.
Can anyone explain how to apply the indirect pressure when a dog is shopping the pile during simple casting drills.
