Match Stats

There's a lot of data in the Racketware app! If you're not clear about the precise meaning of a metric, or want to know what your specific values mean, then here's something to help you make more sense out of it all.

Sessions

Time on Court

This is pretty much the time you spend on court with the sensor, regardless of what you are doing. It measures the time between the first shot played and the last shot played, in one given session. In a match scenario, it will include the warm up and any shots played prior to the start of the match. Similarly, it will include any shots played after the match up to the point that the sensor turns off again and the session ends.

Energy

Energy Used

An easy one this: it's the number of kcals (kilo calories) you burned during the match. We adjust for the strength of each shot, and the time spent in rallies and the accelerations experienced in the rallies. Then it is adjusted to your personal profile accounting for your age, gender, and weight.

When we add these up for your lifetime totals, we count them in mcals (mega calories) - where each mcal is a thousand kcal.

Effort Level

Rallies

Rally Quality

This metric is defined as the average number of shots per rally. The shots counted are those taken by the player with the sensor - this metric does not include shots made by the opponent. In this version it will include rallies that ended with a let or a stroke. It will not include zero shot rallies: which are those in which your opponent serves the ball out, or in which you fail to make a return of serve.

In general rally quality goes up the better standard you are. Typical values for C/D level players are around 2.00.

In general rally quality comes down the bigger the difference in ability between you and your opponent.

Won/Lost % Of Shot Type

This metric looks only at the data for a given shot type (that is: for rallies that end with that shot type), and tells you what percentage are winners/losers. So it answers the question: "if I'm going the end the rally with this shot, what are my chances of winning it?"

Fastest Shot

Keep in mind we measure the racket head speed (at the sweet spot of the racket face) not the ball speed. It's difficult to measure the ball speed without knowing how fast the ball is travelling into the racket and what the angles are. In any event, racket head speed what you as a player have produced - so its actually a more relevant value when you are thinking about your swing and your play. Your fastest shot is the fastest racket head speed we measured.
