We are ready to start stretching the time between rewards to extend the 'sit-stay' for longer.
Still 'sticking' to luring Prince into a sit in the garden until he can do it 5x5 times each time with ease. There are many more distractions in the garden than in the house.
Here Prince is virtually sitting in front of me without being asked or lured in the same session as needing the lure still in the garden. To make training strong it needs 'proofing' by practicing in many fdiffrent environments with diffreent levels of distraction. One needs to adjust one's expectations according to where you are and what is going on.
