1. A method of determining an aim point of a firearm or simulated firearm at a time of firing comprising:
continuously pulsing a laser at a frequency greater than 1 Hz wherein the laser is mounted to the firearm or simulated firearm and is coaxially aligned with a barrel of the firearm or simulated firearm;
continuously detecting a laser pulse location from the laser on a target;
detecting a shot firing event with a sensor mounted on the firearm or simulated firearm;
determining a last detected laser pulse location on the target prior to the shot firing event;
extrapolating the aim point of the firearm or simulated firearm at the time of firing from the last detected laser pulse location and a plurality of laser pulse locations prior to the last laser pulse location.
