Hi
@OvrChkn
A few things jump out at me right away.
**** Your ready position has your arm and bat WAY in front of your body. ****
This makes it longer in terms of time and space to make your backswing/prep for your shots.
**** You seem to not discern well where the slow long balls are going. you often mis-judge the ball to come further out and closer to you. ****
so you are now positioned too far behind and side of the ball... which makes you reach and lose leverage and timing... results in many balls struck out long, since you are way on upswing by the time you impact the ball. When you find yourself like this, the only way to effectively adjust is to slow down your power and loosen your shoulder, arm, and hand... so that you can still land the ball with a little spin and not piss away the point immediately. You did this at 3:03 in your first vid, even though you lost the point, that opponent still had to make an attack and win... he will not do that 100% of the time, but when you go strong on balls out of zone, you lose nearly 100% immediately. you did it again at 3:22... you got ball on table and opponent failed. that is how percentages work. better to get something from the percentages than lose immediately 100%.
later, when you see and discern the impact better, you will be in position better and more often, then you will see the quality and consistency of your shot greatly increase.
*** I see you sometimes like to go for the reverse pendulum serve ***
I would say keep practicing it for the future, but hold off on using it in matches, unless you are just itching to get match practice using it. This serve does not do anything extra for you at this point and it is too risky a serve for no gain.
**** I see you do very well retrieving ball when under pressure ****
Time and time again you give opponent a chance at a strong attack and you bring it back with a soft hand. That is a skill not easily taught or learned.
**** Your fast deep regular FH pendulum serve is getting you what you need ***
When you occasionally do this serve, you sometimes get an error from over eager opponent or get an attackable ball. This is exactly what the serve is for - getting an IMMEDIATE OFEENSIVE ADVANTAGE in the rally, which you expect to boss over and win.
**** On your BH serve, you are moving arm forward way too much ***
You did a BH serve at 3:48 like this and you failed to control it. Consider moving hand and arm accross your body like you doing violin or cutting a loaf of bread. Do this motion with an open bat and it will be way easy to serve short or deep depending on what you want.
**** When you land a topspin and it is blocked, the ball bounces high and your bat prep is way too low causing you to hit the ball out ***
At 1:01 of your second vid you can see this. you made a nice BH topspin to setup the point, but your FH backswing, you took bat down to table height or below for a ball that bounced as high as your chest... the way to fight this is after your first topspin, prep bat at belly button height and be ready... all you need to do then is raise hand and arm a bit, step in, and hit. If you continue to prep bat too low after your first topspin, you will give away a lot of free points this way and crush your confidence if you keep this up.
To be fair to you, I do not know of a single adult who has fixed this the first week they tried.
