Before the experiment average results of control test for both groups were pretty close. After the experiment both groups showed improvement, but experimental group registered better progress, which is statistically verified. The explanation for this is that players of the experimental group could receive prompt information about their technical drawbacks and mistakes discovered, including those that were hidden. Also players could counteract these drawbacks through the use of practice drills.
The experiment proved the assumption that targeted use of special criteria to evaluate the technical skill level of billiard athletes enables setting primary areas and efficient management of technical development.
