Understanding the Basics
How RacketStats Works
Gathering all the stats is one thing, but how do you help your child by looking at all the numbers? Here is a guide to help you focus training on the things that matter most. Of course if you have a coach, that person is the best one to determine what's best.

What does the GRADE mean?
RacketStats produces reports that feature a GRADE for the SERVE, RETURN, GROUNDSTROKES, NET AND SUMMARY. Since these change with the age of the player, you begin by choosing a Comparison Category, Boys or Girls 14, 16, 18, College or Pro. The averages will increase with age. Once the Comparison is chosen then look for a Green or Red Flags. The Green Flag means that the stat is ABOVE the average and the Red Flag means that the stats is BELOW average. If there is no flag next to the stat, that means that it is within the average for the category. You can see what the average is by tapping any FLAG.

How is the GRADE figured.
The GRADE for the category is calculated by the number of Winners divided by the number of errors. Therefore a player can raise their GRADE in two ways:1-Reduce the number of ERRORS in that category.2-Increase the number of WINNERS in that category.

What are the Grade Averages
To make some sense of all the numbers you see, here are the Average Grades between a young 14 and College player. Notice that the numbers get higher, meaning that as they get older they  increase the number of winner and reduces their errors. This takes lots of practice and patience as the player learns when to attack and when to neutralize or defend. Below are the averages we use but keep in mind that all players develop differently and that these are just guidelines for a player's growth. A player that takes up the game when they are older will generally still go through these averages and the goal is to get them first to play at the 14 & Under level before expecting them to play with higher averages

How a Player's Game Develops
Lets get started by looking at the areas a player's game and the assumptions made as each area matures.

Overall Game
Younger players don't hit many winners and make lots of mistakes. As their game matures the number of errors decrease and the winners increase.

Generally, we expect a player to win more points when they are serving than when they are returning. We also aim to get them winning the same percentage of points in both the  Deuce and Ad courts. That being said, We expect that serving to Forehand or Backhand will produce a higher winning percentage but that can change from the Deuce to the Ad courts.

We generally see the Forehand more effective that the Backhand at Returns. What we want is someone who can have a balance between the Deuce and Ad courts. Second Serve Returns should produce a higher winning % than 1st Serves and again it should be balanced in both the Deuce and Ad courts.

The Forehand is eventually stronger than the Backhand, however at the early stages it can be erratic producing winners as well as errors. Backhands as a rule are more consistent producing fewer winners but fewer errors.

When players are young, going to the net is not as successful as later on because their opponents lob can be deadly. However, volleys and smashes must be learned to prepare them for the future. Learning them at an older age can be difficult. So as players develop their net game we expect to see them going there more often and winning a higher % of points.

The Match Report
All points begin with a serve or a return, therefore the key to understanding what a player needs to do rests in the results from these two areas. The printed match report will have what you need. Look for the RED FLAGS!!!! They will point to issues that need attention.

Serve Red Flags
Double Faults - A large number of Double Faults are the major cause for losing serve points, and a highest priority to correct. Its better to get a 2nd serve in and lose the point than to double fault.Ultimately winning Serve points depends on either a players strength of groundstorkes or net play. If you see a RED FLAG for instance in the Deuce Court 1st Serve %, then that issue needs correcting. Are they simply missing it too much, is it poor placement or is it what happens after the opponent's return?

Return Red Flags
The #1 priority is getting the ball back in play which you can see by looking at the FH or BH Returns In Play%. They should be balanced and above 80%. Caution: a player trying to return 100% of returns usually has a weaker return that can be attacked. A balance needs to be struck between effective returns and just getting it back.Now if you notice, for instance, that there is a RED FLAG on Returns from Deuce Court, it will fall into two categories, the player doesn't get the return back or something in the Groundstoke or Net areas.

Groundstroke Red Flags
This is pretty straight forward in that each of the groundstroke areas represent an area that needs to be developed if a complete player is the goal and each involve training specifics. Looking at the Backcourt Points Won/Lost % will immediately point out how good a players is from the baseline. Generally, players can win 40-45% from there, but few win more than 50%. Think Rafa Nadal.

Net Red Flags
The two areas to focus on are on how often a player goes to the net and what is their winning % when they get there. Young players go in less often and win a lower % of points. But as they grow and get stronger both improve and eventually most players will win around 60% of the points when they go in. A RED FLAG in the Backhand Approach area just means that they need work on improving the effectiveness of that approach. Attention should be on developing not only to the approach shots and volleys but their overhead smash.

Summary Red Flags
The SUMMARY will show you just how close the match was and if it is just a handful of points, you need to look at the areas above to see which one is easier to change to reverse those loss of points. Getting the most out of the match statistics lies in knowing that changes in which areas would result getting the best turnaround. For instance they may be good at the net, but don't go often, so do you focus on them going more often, or do you focus on improving their serve or return game. If you focus on where the majority of errors come from, that might be a good start. An area with few winners or errors will not result in much change.
