Why Tennis Analytics

A New Era in Tennis Training!

By Robert Allen Gibson
When I first started looking at Boomer, I was looking for a training partner. I went up to Virginia and tested the machine myself. It was amazing. It brought up many more questions. Is it worth $14,500.00? If I were to win two tournaments, I could pay for the machine. As a tennis instructor/coach, it would take 363 lessons. But with that thought, then came many more questions.

1. Do you think Boomer would benefit you and your students?
2. What is the list of the features?
3. What is the list of the benefits?
4. What would you improve?
5. What is the down side?
6. What can’t it do?
7. How would you use it?

I believed that Boomer could benefit my students and me. It could play me at any level from beginning level to professional. I would always have a partner to play with according to my schedule. My students even when they get better than me could have a challenging opponent. It could extend my career in teaching tennis. The machine is programmable. It gives the players immediate feedback so that they don’t have to look up to see if their shot is in or out. It could react to my shots. It could play my music. It would tell me the NTRP Rating and average speed of my shots.

So what is missing? How could it be improved? What do you think about the Analytics? Do you think the Analytics would benefit you or your students? I thought to myself how does this machine know what to do based on my shots? I wanted to see what made it tic. This machine had a, computer, Speaker system, camera, printer port a spare keyboard port, Microphone port, a USB drive and a spare Monitor port. I don’t use any of those things, what are the potentials of this ball machine?

I bought this machine for 3 reasons; it trains the users to read the ball and not the player; it was $11,500.00 less than Spot shot (a program that tracks the location of the ball during play and calls the lines); it could play full matches with pro’s so that after I get too old I could still work with my Pro’s. Therefore, I started testing its strength and weaknesses. For 2 years, I worked with David Jordon to make this machine a tool that can be a tool for instructors to strengthen the US tennis players. It was great that it told you what is going on, but putting it in print was what really needed to be done to be a great tool. Being able to share a player’s statistics that would be something. If they could review and take, back to their Coach or Pro their performance, that would make a difference in the game of tennis.

I had developed a rating system years ago, that allowed me to rank my players based on the workouts we were doing. Every drill and every point played had a value placed on it. The students really excelled knowing where they stood compared to the others. This system works great for 14 and older but the younger ages tended to get distracted and would guess how many points they had or they couldn’t add up all the points accurately. So how could boomer help? Well this machine has no bias, the shots are in the area or not. The rating system is based on depth, width, speed and to some extent the sequence of shots. Therefore, I wanted a system that would jog the memory/pictures of the players so that they could replay them in their matches. Therefore, we started writing out everything boomer knew, to the USB Drive. This allowed Ruben & me to create a conversion tool to translate boomers information into a database. The raw data was not useful to most players or coaches, so I took the database and started crunching the numbers into percentages about power, speed, depth, width, shot sequence, and types of strokes. These tools allow players to better understand their own game, their thinking processes, allow them to grow faster and go higher in the game of tennis, and excel in life’s routines of managing errors, fixing mistakes, learning about one’s abilities but more importantly learning how to do the impossible and overcome challenges. Here are just 3 reports a player can get out of Boomer playing matches or drilling.

This report is all about Power and speed. The Lower the Boomer level it means the weaker and shorter boomer was hitting the ball. The average speeds show how fast the player responded to the strokes boomer hit. Max speed indicates the potential of the student.

This reports indicates the players control of their shots, are they hitting the ball back to the player or are they moving them on the court. This indicates the player is only having to play half a court and the ball is in their sweep spot at the baseline.

Down Side???

  • Boomer is design to play 1 player singles court. Numbers shifted for smaller court and larger court demenision. Dosen’t do well in Doubles.
  • Boomer reacts to change on his side of the court – a person, a ball, a bird, spider webs in front of the camera, moving shadows on the court, lighting changes.
  • all these issues can be addressed by an overseer/operator.
  • Many people do not understand how Analytics will increase productivity in your workouts, shorten the learning curve, improve understanding of the game.
  • Many people do not understand that this is bringing Professional Statics to the affordability and training levels of future players so that they can work as hard as they need to achive the goals and levels (High School team, College, National Professional, International Professional) they desire.
