UNFORCED ERROR VERSUS WINNER CHART:
This chart takes the basic errors to winners chart to a whole new level. It documents winners and unforced errors from individual strokes through individual games. Tallying which stroke commits unforced errors and produces a high volume of winners will assist coaches in customizing a game plan aimed at exposing strengths and hiding (or fixing) weaknesses.
DEPTH OF GROUNDSTROKE CHART:
This chart will quantify the depth of the groundstrokes, which determines the ease of return for the opponent. A ball landing short in the opponent’s service box is extremely attackable. A ball landing deeper in the court (defend zone) often keeps the opponent on their heels in a defensive position.
ERROR PLACEMENT CHART:
It’s estimated that 70% of all errors are in the net. This chart will expose where the athlete makes most of their errors. One of the keys to error containment is understanding error placement. Winning matches require spotting and fixing re-occurring errors.
ENERGY MANAGEMENT CHART:
This chart effectively identifies the emotional climate of the athlete throughout competition. Recognizing how often the athlete unknowingly shifts from their optimistic mindset to a pessimistic mindset is typically the precursor to a significant drop in one’s performance level. A common factor is that poor play starts with a negative mindset shift.
