i think the failure to loop everything long is of course something that would hinder somebody from making the next step in quality, but i would not have thought that it is still an issue with >1600 USATT rated players or is that rating only what you suspect the opponent to be ?
Since i am not allowed to "Judge" in here, i would add some own footage for the discussion and it is really something that bothers me from time to time in matches and makes me lose trust in either my ability, grippiness of rubber in humid conditions or stamina.
I had a league match day in a gym that was quite hot and moist. Even though it happens only perhaps two or three times a match, inside the match it makes me uncomfortable because my main "tactic" is indeed to loop the long push receive of the opponent after my serve.
Sometimes it just happens that i fail to create enough grip with the ball and it flies into the net.
I have added a video with a few of these situations where i can not pinpoint what happened in that exact instance, when in similar situations seemingly with the same move the ball goes over the net properly.
I am the guy in the red/black shirt.
No you might say "hey, you did not learn the topspin technique well enough" and even though my topspin movement in games looks very different than if i practice the right technique, it is sound enough to reliably loop most underspin balls.
As proof of my ability to usually loop the ball over the net reliably here is a snippet of just one game i had against the opponents "strongest" player which really was just a little over 1100TTR but i would not take anything away from him because his game was basically being a lefty serve to the wide forehand with a no spin ball (with a kinda backspin movement) and then smash the high return.
You might get the impression that my opponent can not block at all, but i assure you when they were warming up he reliably blocked the loops of their youngster over and over again.
In this game basically i did wrong what Novarac also did, which is instead of looping that serve i tried to push or chop it. The later worked in around 50% of the times, but of course instantly looping it would have been better.
The opponent was having trouble to block my short opening loops and then tried to smash them at times. It worked perhaps 3 times, but usually the smash would go out.
I won that match in the fifth, but with proper discipline and tactic i probably could have won in three sets:
So TLDR;
what is the difference from the failed to loop the ball over the net compared to the other examples you see where it simply works?
I can not make it out and it is immensely frustrating if i begin to doubt my main weapon inside a match.
