Are you saying it is clear that your racket is going low to high in that video where you only see the racket after it hits the ball?
Oh, okay, I see. Thanks. You are right, it is clear and obvious to see that in that video where you can't see your stroke, that you are swinging, uh, did you say, low to high? Is that what I am supposed to say.....boss? Oh yeah. You aren't paying me. I don't have to tell you what you want to hear. Okay, sarcasm over.
And in the other video where your stroke can be seen you are generally hitting the ball flat, with the racket faced open and then after contact you pronate your forearm so your wrist faces down and often your elbow goes up a bit. Classic flat hitting style.
But the answers to all your questions have actually already been given. Your contact is direct. There is almost no "tangential" as you like to call it. If you look at your serves you can see it too. Your racket there is faced up for backspin but you hit into the ball instead of brushing and pulling past the ball (tangential, that is what you mean by that term, right). With both your "topspin" stroke and your "backspin" serve, if there was a proper amount of "tangential" your racket would start further back from the ball and end up past the ball which is why in Chinese the word for a loop would literally translate as: "pulling past".
In the end, we are all better off if you learn to do this so you can FEEL what we all seem to be able to see which you don't seem to be understanding.
Here is a project for you. And I do think this could help you and actually get you to be a better player and a better person. I know, perhaps I am a fool for thinking someone can grow up and change. But I can hope.
Make a few new videos. Make one from the side like you have already done but include your whole body and your stroke in the video so the mechanics of your stroke can be seen. Make another from the same angle as the angle you have in the serve and receive video so you can see the blade face on contact. Make the videos with a better quality camera. I have heard you talk about having good video cameras. Make it good enough quality so the images can be stopped frame by frame so you can grab images of the exact point of contact and see your blade face's angle. I actually think that could help you.
In the serve and receive video, one thing I noticed is that, you are actually much better on the lower balls. The ones that are lower your contact is much better. And you get some spin there.
Try one more video. Make the same spin and speed from the Newgy machine but make your contact point below the net. Make it so we can see your stroke: I would make that one from the same two angles. Just try it and see what happens. There really is a reason why so many people are seeing the same thing.
By the way, it is true that there are a couple of balls that go back with some arc and a bit more spin. But I would still say those balls do not have enough spin to call them a loop. The balls are fairly slow. And they do not arc enough or soon enough for how slow they are. And they do not kick the way a real loop should.
If you look at NextLevel's loops again, there is a lot of power from his body in those loops. They have a lot of pace. And they still arc onto the table and kick. When a ball is going fast and has a lot of power behind it and it arcs like that, there has to be a high level of spin on the ball. And when you look at some of his matches, when he loops, his opponent often has trouble tracking the ball because of the trajectory of that arc with that speed. Those are pretty decent loops. There is a very big difference. And I have to give it to NextLevel for showing how, with injuries and real limitations he has gotten to be pretty darn good for a guy with such bad knees that make it hard for him to move, and to get low. Both of those things that your knees, when they are good, help you do, make getting good at table tennis much easier when your knees do them well.
With a different attitude and on line personality, people actually might be telling you positive stuff about yourself. But that doesn't usually happen when you are calling everyone idi_ts, as_holes and st_pid, as frequently as you do.
But, here, here is some material for you to ruminate on:
We are actually all seeing something that you seem not to understand. If instead of thinking everyone else is wrong, you tried to understand what we are seeing, it would actually help you improve your level. In the end, I actually think that would be pretty cool.
There is a real reason why this last one is so funny:
