Camera vs. Shimmer

Below is a graph of the distance (in pixels) that a ball travels following a strike from the cue vs. the strength exerted by the player on the cue.I recorded myself for about 10 minutes striking a red ball down the table (red for good contrast against the blue surface) at different strengths, some soft some hard. The shimmer was attached to the cue and reacted to a strike by a sudden spike in its data values, particularly on the y axis. The data was then processed by cutting before and after images of each shot out of the video and measuring the distance between the ball's positions, the shimmer data was exported to Excel (this resulted in approx 42,000 rows X 3 columns (x,y,z axes)). With Excel, by plotting graphs I identified the shots. While experimenting, to serve as a divider between each shot, I shook the cue vigorously. Once I identified the shots,I took the difference between the max and min values of y axis and plotted this vs. the distance calculated.

The following graphs illustrates this:
