It’s not about the 1/4” out - if you have someone that does a 1/2” grouping with all 4 shots for the shooting test 1/4” below the circle then surely an assessor with any sense can see that a) the person is a capable shot and b) all four shots would result in a dead deer. Failing someone in that instance would be silly.
My point being if the 4 shots were in the area of the yellow marking it’s still a dead deer, some people shoot low heart, some shoot pinning shots, some shoot centre mass (which it seems is the DSC preference) but all three areas will be dead deer.

If a person was shooting and at different sides of the circle I’d be more concerned than someone shooting a 1/2” group that was 1/4” below the line of the circle.
