How can you tell when someone improved? Talking about already intermediate players. Their playing style stays and looks the same, their footwork is probably the same other then moving faster. Smashes will only be faster and more depth, but you have to be on the court to see that. Drops and lower, but they were already low in the first place + you have to be on the court. I seen people like this who have been training for a while but I haven't noticed their improvements. I also personally experienced this because no one had mentioned I had improved at all, which might mean I haven't. Would their improvement be not as obvious as beginners. Would you not be able to tell they improved? Or would it be harder to tell?
