There are two kinds of racquet maps in TWU - power potential and shot speeds. The former increases towards the throat, while the latter increases towards the tip, and the optimal hitting area is where the best compromise is achieved. Obvious question then is: why is a combined metric not shown as a map? It will be useful for two reasons: 1. To compare the overall power map between two racquets 2. To find the "sweetzone" for a particular racquet and see if it matches the hitting habits Is it because the two measurements are "apples" and "oranges" and so cannot be sensibly combined into a single metric?
