Average Trace Speed Graph highlights your S1 (mm/s in Pro) taking all the shots into account rather than just one. Mistakes and shortcomings are quite evident when you analyze a stand-alone shot, but the macro pattern is not always easy to grasp when you got several strings in front of you.

If you do jerk the gun in a specific manner or make one recurring mistake during the shot release - all that will come to light with this graph. Ideally, you want to see the graph plateau in the last 0.5 seconds without any obvious spikes. If we are talking dry-fire, it's a good sign if this plateau persists for some time after the shot release too.

The y-axis highlights the average speed of your Aimpoint (in millimeters per second) across all shots and the x-axis shows your control interval (in seconds).

In figure 1 you can see the graph of a shooter who could use some improvement in terms of hold stability. If you pay attention to the S2 segment of the shot, you can notice that the graph visibly ramps up starting from ~250 milliseconds before the shot and onward.

In figure 2, however, not only is the average speed significantly lower, but the graph itself evens out and flattens as the moment of shot release approaches. The graph stays relatively parallel to the x-axis for another ~100 milliseconds indicating solid control over one's hold even after the trigger is pulled.

When looking at the trace for an individual shot (as in the examples above), it would be useful to superimpose the speed graph for that shot on this average speed graph for the series. It would show whether the individual shot was typical (consistent) or untypical (poor or very good) relative to the other shots.

Sir I also agree that this would be a useful addition to our software for analysis and error correction purposes.

If the current format for the graph (grey above the average line, pale green below the average line) is maintained, then just a single line in a stand-out colour (red/dark blue/dark green) should be used to indicate the speed of the current (highlighted) shot.
The vertical scale should be the same whichever shot is being displayed, so that the scale does not change as you move through the sequence of shots. The vertical scale used may need to change depending on the discipline (pistol/standing rifle/prone rifle) and distance (10m/50m/300m/etc.) selected, but should be consistent (remain fixed) for the whole file, and ideally for all files of the same shooter, and preferably even between other shooters of similar standard (so that files and performance can be compared).
