When you are done with a training session we want to let the horse know we’re done. We’ll do this by leaving a “jackpot” (a large pile of the food you’re training with). We’ll do this to put a magnitude reinforcement for the entire session - letting them know they did a great job. This also make it so that ending the training isn’t punished. So, they don’t see going back to their home or us leaving as a bad thing at the end of the session, making them want to avoid whatever they think they did last to make us leave.
