The first competition was held without random bonuses (only national ones), all subsequent ones will be held with them. In addition, each country has 10.0 skill units that it can distribute throughout the event, but no more than +3 per athlete.
If desired, you can give them names, role-play, etc. Or you can skip this.
The player can also use doping on their athletes (scientific progress is taken into account, the minimum value for this is: 65, each unit above adds +0.075; allied states can use the allied state's scientific progress; for example, Rex Ventorum and Qasardastan). You can use it as many times as you like, but if this violation is detected, the athlete will be disqualified (I chose law enforcement agencies as the control point; in the case of Tarpaulin, the chance of detection will be 17%).
