The application is intended for a "referee" or "coach" located at the level of the posts to observe on the top line, the L team (like Left) and the bottom line, the D team (like Right). The score is read in the direction of reading in Thousands - Hundreds - Tens - Units in order to be able to quickly recover the score. Also, there is the possibility to visualize in percentage of success in each level in order to help the students to become aware of their current levels of practice.
