Transitioning between target arrays separated by 90 degrees or more. These large-angle transitions require different mechanics than close transitions -- the entire upper body must rotate, and for extreme angles the gun may need to be pulled in toward the body to shorten the lever arm. The same eyes-lead-gun-follows principle applies, but the body rotation component becomes dominant. Wide transitions are where matches are won and lost.
For transitions of 120 degrees or more, elite shooters pull the gun toward their body during the transition and push it back out as they arrive on the new target. This shortens the lever arm of the rotation, making the gun easier to decelerate and eliminating the over-transition that plagues wide swings. The physics are simple: a shorter radius produces less rotational momentum, which means less overshoot. This technique does not exist in close transitions -- it is qualitatively different.
