For combat striking, the two most important metrics are count (number of strikes) and force (intensity). The Impact Score is a composite of those key numbers. Because we don't measure force directly, like hitting a pressure plate, we had to find an indirect way to measure intensity. Good striking technique is about hitting *through* a target and not *at* the surface of the target. Therefore, hitting through a bag hard will accelerate it quicker than hitting lighter. That is what we measure for each strike. The Impact Wrap Tracker measures the acceleration of the bag and puts a point value up to 100 for each strike. The harder you hit the more points you get and the points keep accumulating.
