So I did some research, and learned that there are actually a number of different, and sometimes conflicting theories about how sniper's should train , and how much thought to put into ballistics tracking. As an aside, I really want to go to the GPS Sniper Training School - I am not in any way endorsed by them, but it looks fun. It didn't take long for me to get in over my head, and then I figured, that probably the most helpful app I could write, would be one that helped me calculate spread, grouping density, and cluster metrics for accuracy training.I really liked the look of this target, inspired by the Aguilar training system





So I decided to program it into the TouchShield Slide





The app is pretty straightforward, it lets me keep track of the shots I take, and then I can do analytics and measurement stats on the Open SciCal calculator . This is a pretty sure-fire guaranteed way to look like the biggest nerd at any firing range across America.



It took me less than 15 minutes to write that code for the Arduino and TouchShield Slide, and I had a lot of help using the function reference over here at the liquidware wiki. The functions are all inspired by the Processing programming language, so it's intuitive to pick up if you've ever written graphics for
