Session with Sony Smart Tennis Sensor

Interesting, I wonder if that is true ?
Currently available sensors provide numbers with a spread around 20 percent aInteresting, I wonder if that is true ?
So a readout 80 miles can mean 70 or 90
Just to keep you warned
The swing speed is consistent with my radar gun that tracks racket speed. It didn't seem to change the max speed whether I removed or added weight. What did change the speed was when I used a racket that was one inch longer. With the longer racket my maximum swing speed increased on ground stroke swings. (I never set the swing speed radar up for service motion clocking, so I don't have any info regarding added weight compared to no added weight.) With the Sony sensor I think the read out for swing speed should be accurate.Interesting, I wonder if that is true ?
Based on TW's comments, the sensor's ball speed rating is close to playsight's speed readouts.

It estimates a speed of a ball,to the best of my knowledge

There are 3 notions :
A racket speed (the term used by you)
A swing speed (the term used by Sony)
A ball speed
so the first question is: is the first the same as the second?
Is it obvious to everybody at the Forum minus Suresh that a ball speed is always smaller that
a racket speed?
Just for the record it is not obvious to me
You may want to read post number 55Less compelling then it sounds..these negatives. RHS major factor - and the sensor measures these really well. When they rolled out the radar to compare - it was fairly accurate..

Radar gun can certainly track racquet speed FWIW. But they have tested the sony sensor against radar and it does work even for ball speed.. Once you know where the ball hits on the racquet - the spin number and the RHS you can make a pretty good guess of ball speed. On serves should be near perfect.

I do not know how the radar gun can track racket head speed.

I used the term racket speed to mean swing speed. This was the radar gun used to measure swing speed. http://www.amazon.com/Sports-Sensors-Swing-Speed-Radar/dp/B00124P7SI
Ball speed can be greater than swing speed. Ball speed can be less than swing speed. Ball speed can also be equal to swing speed. This really depends on the ratio of spin to pace you use when hitting the ball. I can achieve all three of these outcomes on my forehand side with the Sony sensor.

As a master engineer what would you do in this case without using optics? Would reading vibration responses from the racket with sensor work to detect impact location? First start off creating a database of rackets and input a bunch of frequency ranges that correspond to its respective impact location. Then once the sensor has its own impact data from a users hitting session, the user can upload that data to a software package. Next just use a lookup function and match the frequency to a frequency impact location table.
Can you consult with those who have PhD in engineering on how they would handle this situation or know if this explanation actually works?
This is not the first device that someone created that tells the impact location. I have seen a video of someone in Japan use a device on Youtube that was able to detect impact location. Also, there was another video that looks like from India doing the same thing on Youtube. Both of these videos are old and I don't have the urls to them.

How much I do not know
It should be considered in all of those discussions
The same should be considered for the swingweight

Adding a sensor is changing a balance of a racket
How much I do not know
It should be considered in all of those discussions
The same should be considered for the swingweight
Balance of the racket during testing was four, seven, and nine points headlight. Swing weight was from 320 to 376. Initially my swing did slow down on the serve at 376. The loss was around 4 mph on the serve swing speed. Eventually I got stronger and that number became the same as swinging with a 320. Now my 320 hasn't gotten any faster, and it's at the speed as a swing weight of 376. What is noticeable is that to generate the same speed with 376 compared to a 320 is it feels stressful on the elbow. Maneuverability is also noticeable, but the sensor number for that is less obvious.
I think there is an individual limit on when swing weight that does actually slow down swing speed. It is just that I have not boosted it high enough yet. As for the racket balance, that did not seem to matter in terms of swing speed.

Before putting the sensor on the balance was,say, 9 points head light
After putting the sensor on the balance is,say, 7 points head light
(I am guessing here)
So technically it is NOT the same racket.
Just to put everything in a bit different perpectove I play Babolat Pure Drive Tour which according to TT
Is 9 points head light with the swingweight 323
I just gave checked the number
Purpose of starting the test was to check what was going on with my varying service swing speed, and find out what I needed to do to keep swing speed above 95mph.
Base racket: Wilson Blade 98 18x20 320g, 327sw, 4pts head light
Test info (Sensor weight balance included in specs listed):
7 points head light was at 327sw(327g), 345sw(361g), 376sw(371g). 9 points was at 380sw(377g). Test was conducted with three 2015 Wilson Blade 95 18x20 weighted differently. One of those was at stock weight at 320g with a swing weight of 327. After putting on the sensor it was 327sw(327g). All the 7 points head light was with the sensor on. 9 points head light was with the sensor on.
The Blade had a lot of weight at the tip with an asymmetrical weight distribution from 3 and 9 o'clock using head tape. Grip used was Wilson Shock Shield Hybrid with overgrip. I added sorbothane under the grip to make it more head light on one of the Blades.
Also did a test with a completely different racket. Specs with sensor on the Yonex Vcore Si 98 was 8pts head light with a swing weight of 313 and weighing 332g.
Did another test with Yonex Vcore Tour F 97 (290g). Specs were 6pts head light with a swing weight of 309 weighing 312g
Results were same maximum swing speed.
This test also provided info on how weight and swing weight effects swing speed. With the lightest stick and the lowest swing weight I did not gain any swing speed. It remained the same on serve at 103mph swing speed. Max peak speed with the Blade 376sw(371g) achieved the same max serve swing speed at 103mph.
Impressions:
The Blade felt like swinging a hammer at all balance points and swing weight except at 327sw(330g) while the Si 98 felt just like a regular head light racket.

Let me explain why I do not understand.
There is a conjecture that rackets closer to the even balance do have better racket head speed. There were some British simulations to prove that.
The problem is that a racket should be good for all three strokes so the even balance is not really a good solution.
Now we are entering the difficult part of the conversation- I would suggest to try
a racket with a 2 point balance to see whether u can achieve any improvements

Ground strokes I think I am bound by physical limitations. I can't swing above 93mph on the forehand side. Serve I think can still go up, but this is more an issue of technique and not the equipment.
If I take off the Shock Shield hybrid grip then it will be closer to even.
From a playing stand point I would not really want to do that because I want to maximize comfort rather than performance.

You are warned not to blame Julian
A hybrid with hut in mains should be ok
Is 103 from the Sony sensor?
If yes it a swing speed?
103 was from the Sony sensor.
Ball speed for that swing speed was 115mph(Blade), 112mph(Vcore Si), 110mph(Don't remember), 107mph(Don't remember), 106mph(Don't remember).

You may have a scenario that making the balance more even will improve
the speed of serve but t will decrease the speed of forehand.
It may not happen in your case
I do not know what the Shock Shield grip is
Using gut could help around 5 miles but may kill the mechanics

Playing preference:
I wasn't looking to maximize comfort from the strings. For the strings I want the feeling that the ball compresses and flattens losing energy from the deformation process.
I do not trust so much the Sony sensor103 was from the Sony sensor.
Ball speed for that swing speed was 115mph(Blade), 112mph(Vcore Si), 110mph(Don't remember), 107mph(Don't remember), 106mph(Don't remember).
If you can have an access to a good quality radar gun it could help
Btw. 115 is a very high number
I was misunderstood.
You may have a scenario that making the balance more even will improve
the speed of serve but t will decrease the speed of forehand.
It may not happen in your case
I do not know what the Shock Shield grip is
This is Wilson Shock Shield Hybrid. http://www.tennis-warehouse.com/Wil...cement_Grip_Black/descpageWILSON-WSSHGBK.html
It is a replacement grip from Wilson.
I was misunderstood again.Playing preference:
I wasn't looking to maximize comfort from the strings. For the strings I want the feeling that the ball compresses and flattens losing energy from the deformation process.
Gut is perceived as a more powerful string
Gamma Professional is pretty high on a power scale
I use Gamma Spin a lot as well
I do not trust so much the Sony sensor
If you can have an access to a good quality radar gun it could help

Number is kind of average. I've seen higher numbers from Japan serve competitions with the Vcore Tour F 97. The winner was around 190s km/hr.
Once more: try to talk to a shop to check whether you have the most powerful setupThis is Wilson Shock Shield Hybrid. http://www.tennis-warehouse.com/Wil...cement_Grip_Black/descpageWILSON-WSSHGBK.html

I've actually gone to using Prince Tour XC gauge 15 (1.40mm). Complete opposite in terms of power from the strings. I haven't installed it on any of my preferred playing racket yet.
I do not mean to be rude but note km/ hour in your e-mailNumber is kind of average. I've seen higher numbers from Japan serve competitions with the Vcore Tour F 97. The winner was around 190s km/hr.
I have tried to respondkm/h read 185 on mine. I started the conversation. At TW. Your inbox should have an alert.

I have never used Prnce strings,very sorryAre new strings lowering the speed of serve.
I have not put it on a racket that is compatible with the sensor. But what I did notice was it's much easier to get the serves in. The racket I installed it on was a Graphene Prestige MP at 57lbs. Dynamic Tension number was 44 on the ERT300. I really like the response from the strings so far. Now I am just going to wait until I bust my old strings on the Blade.Are new strings lowering the speed of serve.

U may have a classic potential for a conflict between higher percentage of serve vsI have not put it on a racket that is compatible with the sensor.

I have to run an errand- nice talking to u

At the moment I want to keep the speed with the higher percentage while I work on increasing speed through technique.
For increasing speed I want to increase vertical jump and translate that ground force into the serve.
I do not know how the radar gun can track racket head speed.
Just for the record I have an engineering degree
Yeah okay. All you do is aim the radar gun at the bat/racquet etc. For example..
Figuring out where on the racquet face the ball hits is trickier - but the vibrations are enough for pretty good results. They have some smart people figuring this stuff out..
