Wow… This surprises me. I knew of a handful of teams throughout the season who effectively used camera cross hairs. 1507, a shooter powerhouse at Finger Lakes, won the regional with those cross hairs. I believe I heard at one point 217 was using them as well, and 67 had borrowed the code for them for some time (thought this may be incorrect. Memory doesn’t serve me well nowadays).
But I never expected 1717, one of, if not the, most precise shooters in the world, would use them. This really convinces me that you don’t need complex systems to do well.
