Hi Maurice, developing consistency is a key area for sure and using a robot and playing regular drills will help of course so that’s good. Playing slow and controlled will improve the consistency but it is important to be able to play a lot of balls on the table at closer to your full speed too.
Irregular and random training will definitely help in this area too as you learn to adapt and change quickly to different ball placements and switch faster your body position etc. Then when you go back to the regular drills or the robot it will feel much more comfortable and easy. So I would say add in these types of drills as well as keep going with your regular consistency training and over time it will improve 🙂
