1. A method for determining a performance metric based on a discharge event of a firearm, the method comprising:
receiving, by a first event detection module associated with a first firearm of a first user, a plurality of first input signals over a sample window of time from a first inertial measurement unit (IMU) configured on the first firearm;
identifying, by the first event detection module, an occurrence of a first shot discharge of the first firearm at a first time based on the plurality of first input signals;
identifying, by the first event detection module, an occurrence of a second shot discharge of the first firearm at a second time based on the plurality of first input signals;
determining a first split time for the first user based on a difference between the first and second times;
associating the first split time with a scenario parameter; and
determining whether the scenario parameter has influenced the first split time.
