I just want to see someone playing at a high level that has played for so little time as you have. I may need to reconsider my project if you have reached a level like that because I play a lot and maybe table tennis is not for me. My goal so far has been to not lose against people that have played less time than me, and I have never met anyone yet that has played less time than me that has beaten me. To me, rating means nothing. My coach has been a national level coach in Sweden and when he was in talks with one of the best Norwegian tennis players, Casper Ruud, he agreed that rating has absolutely no say. So I prefer looking at someone play and to see the timing and the balance. I lose a lot of games because of the effort that I have put into the game brings me to a really bad mood when I cant perform in ranked games. Its about mental rigidity in many ways. My hands feel like jello just typing about it now.
Here is recent video of me doing multiball training:
I watched some of your videos, I think you're perhaps focusing too much on maximizing what your technique allows rather than improving your technique. This may be driven by your strong desire not to lose to any other beginner.
I'll share an example of the beginning of my TT play. Here's an early video I took of one of my matches, some 11 years ago about ~8 months after I started playing. My opponent played a lot of tournaments back then and was consistently a 1700+ player. I had no coach, just practiced against a wall and played at this dinky club, but I got advice from message boards and set out to improve.
This was 3 months later, against the same player. You can see how much my form changed, and my footwork improved a lot too. By then this old guy was no longer my match.
Looking at your videos I don't see much improvement in your technique, you're just getting more consistent with your existing technique. Changing your technique will cause some pain, particularly since you've been playing that way for at least a year now, but IMO it's worth it and as long as you're willing to tough through it. It'll be worth the short term suffering, including possibly losing to those who have played less than you.
