Technical shooting analysis
Noptel ST-2000 products measure accurately the gun orientation path on
the target surface both before and after the shot, and record the shot
itself. This path indicates how the shot was generated. No two absolutely
identical paths exist, i.e. each shot has a unique history. On average
the gun orientation path forecasts the resulting score with remarkable
accuracy, and it in fact contains almost all the information required
for the technical evaluation of shooting performance! We at Noptel have
collected tens of thousands of shots from shooters at all levels of skill
and have developed a model to analyse the skill of shooters in an objective,
reliable and understandable way.

The shot model
The success factors and their interconnections are described in the shot model.
The shooter's hold reveals his ability to control his muscles and prevent unwanted
movement. His aim reveals the accuracy with, which he is able to direct the
gun at the desired point on the target, and trigger control reveals the timing
of the actual triggering event relative to the hold/aim process, and also the
cleanness of triggering. The success factors interact with each other. The key
position is occupied by the hold factor, which is linked to the others and to
the result itself, i.e. it affects the result both directly and through aim
and trigger control. In addition, the result may have a counter-effect on the
hold etc.
Our NOS shooter training software makes it possible to analyse the success
factors both graphically and numerically.
Effect of success factors on the result
|
Holding instability and aiming inaccuracy will
reduce the actual achievable result level, while trigger control can either
improve or further reduce the final result. The characteristics of the discipline
define the role of each success factor. Holding ability has the greatest
role in a standing position and in pistol shooting, for example, whereas
the major element in military prone shooting is aiming ability. |
Measurement of holding and aiming ability
The fastest method for analysing a shot is to observe the basic target replay.
The small blue cross shows the average gun orientation point, e.g. the aiming
point during the selected statistical time (here 3 seconds). The green rectangle
illustrates the area of gun movement horizontally and vertically, e.g. the holding
area of the shot. Both aim and hold statistics are also available as numerical
values.
Graphical hold analysis
Holding skills can be analysed by observing the extend and symmetry of the
movement (the hold box). Asymmetry in pistol shooting may indicate problems
with shooting position, grip or muscle condition, for example. The picture illustrates
four holding skills in basic target view. Logically, the shooter having the
smallest area of movement will have the best basis for good results.
Graphical aim analysis
The Centre of Gravity - COG - is shown as a blue cross in the middle of the
green hold box. The cross should be found in the middle of the target if the
aiming picture (the sights with respect to the target) is correct. The next
picture shows examples of good and poor aiming together with good and poor holding
ability.
Graphical trigger control analysis
Triggering ability is easy to analyse using different replay views. Here the
same shot is illustrated using the basic target and R(t) -replay views, revealing
a bad jerk. The red arrow shows a bad triggering curve, which is quite different
size and form from that of the hold stage. The triggering clearly introduces
extra energy into the movement.
The trend curve of a average shot
 |
The trend curve discloses the style of a shooter.
The chart tells us how the average shot develops in the last 3 seconds for
air rifle and air pistol shooting, and the last 300 milliseconds of this
represents the reaction time, when more or less optimisation appears. A
shooter can be a holder, an optimiser or a reaction shooter. The following
curves are measurement results and show the average trend calculated for
hundreds of shooters. |
Numerical skill analysis
|
The success factors are also quantified and can be used to compare shooters
or to trace a shooter's development in time. The numerical box can be observed
in the basic target view in order to obtain additional, more specific information
for analysis. The first two values are for the hold, the next two are for
the aim and the last two are for trigger control.
