In risposta al quesito di diamante:
http://www.issf-sports.org/theissf/championships/olympic_games.ashxHow to qualify for the Olympic Games Since 1988 the Participation in the Olympic Shooting events is not guaranteed. Each national shooting federation must earn "Quota Places”.
The quota place distribution for the 2012 Olympic Games of London will start in the year 2010.
Participation
Before an athlete may participate in the Olympic Shooting events the NOC must have earned a "Quota Place".
Quota Places
Quota Places are generally awarded when an athlete wins a gold medal at the ISSF World Cups, or achieves a high place at the World Championships or at a Continental Championship in Africa, America, Asia, Europe, and Oceania, in the three years preceding the Olympic year.
A Quota Place guarantees that someone from a given country, not necessarily the athlete who earned it, may compete in that Olympic event. Each athlete who wins or obtains one (1) of the following named places in the Olympic events obtains one (1) qualification place (quota place) for his/her NOC in the Olympic Games.
The maximum number of qualified athletes is 28 per NOC,
the maximum qualification per event is two (2) athletes per NOC, except in the Trap and Skeet events for women in which the qualification is limited per NOC to one (1) athlete only.
One (1) athlete can obtain only one (1) quota place for his/her NOC in any event. If a quota place is won in an event by an athlete who has already won a quota place in any event, the quota place will be granted to the NOC of the next ranking athlete.
Each athlete, however, who has been entered in one event in a quota place by his/her NOC can be entered as a double starter in other events if he/she has also obtained the Minimum Qualification Scores (MQS) in the other events. NOCs are not allowed to enter more than two (2) shooters in any event.
On request of an NOC/ISSF Member Federation, one quota place in one event can be changed for one quota place in any other event if available.
Unused quota places will be reallocated by the ISSF and the Tripartite Commission. Where possible, they will be reallocated to the next highest ranked athletes at qualification events from NOCs not already qualified.
