What is electronic scoring targets (est) in Shooting?

Section 6: Scoring

Qualification: Integer scoring (whole numbers). The target has 10 concentric rings; the center ring scores 10, the outermost scores 1. A miss scores 0. Maximum per shot: 10.
Finals: Decimal scoring with tenths. The 10-ring is subdivided: a perfect center shot scores 10.9, with 10.0 being the outermost edge of the 10-ring. This gives 0.1-point resolution, critical for elimination rounds.
Inner tens (X-count): In qualification, shots in the innermost circle of the 10-ring (the “X-ring”) are recorded as tiebreakers
Maximum qualification score: 600 for 60-shot events (air rifle/pistol), 1200 for 120-shot events (3 Positions)

Each target is scored as a hit (1) or miss (0)
A “hit” requires a visible piece to break from the clay target as determined by the referee
Maximum qualification score: 125 (125 targets, 1 point each)
“No Bird”: a target that malfunctions, is launched incorrectly, or is broken before the shot — the target is re-thrown

EST systems use acoustic sensors to detect the exact impact point of the pellet/bullet by measuring sound-wave timing from multiple microphones
Scores displayed instantly on a monitor at the athlete’s firing point and on broadcast screens
EST systems are calibrated before each competition and verified against reference shots
If an EST malfunction occurs, backup scoring (paper targets or manual inspection) may be used

Top 8 (rifle/pistol) or top 6 (shotgun) from qualification advance to the final
Qualification scores are not carried over; the final starts from zero (since 2018 rule change)
Athletes fire in designated series; after a set number of shots, the lowest-scoring athlete is eliminated
Eliminations continue until 2 athletes remain; the final series determines gold and silver
Medal ceremony positions: 1st (gold), 2nd (silver), 3rd (bronze — two bronze medals awarded, one per eliminated semifinalist)
