I totally get it. That I have a flawed technique and I agree to that. Even the people I do play some of them who I lose consistently and are better players in general, they too have flawed technique but even with those flaws they have some shots or tricks up their sleeves which makes them win at this amateur level.
I was rating me on the similar scale, even with these flaws , I can put the ball on the table. My frustration and rant was on me as I have played with that guy earlier and have defeated him and I was more pissed with the fact that even when I figured out what I was doing mid game why I did not change tactics and was frustrated with other people loud talking. I might even have lost but would have been a little content that I was clear with my actions even if that resulted in a loss .
Now coming back to you valid point, yes I have made some changes
1. Got my paddle proper moved from Pre Made paddle to the my proper setup. It does help for sure.
2. Have I gone better, I am not sure. I am hitting the ball sometimes and brushing it sometimes. I try not keep twisting my wrist to weird angles (which I got a feedback) but I with muscle memory I still do that. But now whenever I do that I understand that what mistake I have done and try not to do that for next few shots before I again do due to being in the moment of placing the ball on the table.
I don't have any latest video but surely I will get some soon and post for the reviews. If I have gone a hint better or still doing the same mistakes with no improvement.
Again this might sound mean but I don't mean it to be - it is just some harsh realities that if you accept will be helpful in the long run to prevent frustration and improve.
What we saw in your recent video, no you cannot put the ball on the table with any consistency at all. You couldn't consistently make more than 3 shots when someone was slow feeding the ball to your forehand so that means without doubt that there is no way you can put the ball on the table with any regularity in match play or random scenario.
So there is a difference there between what you think you can do and what is actually happening.
Yes you can play the game with flawed technique but not when the technique is
that flawed. In your video from a few weeks ago, you fell into that category. And what this means is that, at that level if you win a match one time against someone that shouldn't make you think there should be an expectation of beating them again. Because at that level neither player is good enough to really dictate a single thing that happens in the game.
The good news is that the only way is up from here. I look forward to seeing your next video and will try to offer whatever advice I can.
