On target transitions I've observed that sometimes even if I am staring a hole in the target exactly where I want to shoot, it can lead to me underconfirming (firing when I start to see my red dot enter the target vs waiting until it reaches the spot I'm trying to hit). Because the cue to fire changed for me from looking at the dot and waiting until it is centered, to looking at the target and waiting for it to appear, it's taken me some getting used to in order to have the right timing.
