Group Size Calculator Description

Group Size Calculator application was designed to calculate some group statistics of a number of shots fired on a target. If you have a scanner available to you, it makes it very easy to capture the X-Y locations of your shots simply by opening a scanned image of your target and clicking on the bullet holes! Alternately, you can measure your shots with a caliper, enter the X-Y locations of each of the shots into a text file, and feed this file into the GSC to get the group's statistics. The GSC provides the following information for the group: ■ Group Center ■ Group Size - largest distance between the centers of any two shots. ■ Mean Average Distribution - the "standard deviation" of the group ■ Average Radius - average distance of the shots from the center of the group. I believe this, when used with the Radius Standard Deviation, to be the best measure of how well a particular load/gun shoots. ■ Radius Standard Deviation - statistical measure of the distribution of radaii Limitations: ■ nag screen
