I recently shot a Tier 3 match where a competitor failed Chrono by not making minimum power factor. The chrono officials said he had a DQ and called for the match director as per rules. The match director shows up and talks to the competitor and chrono officials then allows a reshoot with the competitors back up pistol. The guy had shot over half the match with the pistol that failed chrono yet he was allowed to continue the match for score after the back up pistol was used to pass chrono,the pistol appeared to be the same as his primary. Should this have stood as a DQ or should he have been allowed to continue the match?
