Hey Andreas, being more relaxed will absolutely reduce your error rate in the long run for sure! I think the things you have mentioned above will all help, especially doing lots of drills where you focus purely on consistency and playing nice smooth controlled shots. Playing a slow pace is great and focusing on spin and brushing the ball well, this improves control and feel on the shots and will help you be more relaxed too.
Always try to think spin over speed as well in all the shots you do, but you are doing the right things, maybe just see how it goes with the slower blade, sometimes it’s easier to actually be more relaxed with a faster blade. But that is a matter of personal taste with the equipment and what you feel comfortable with of course!
Tom 🙂
