The barrels have 'convergence' because if they were parallel, the fact that each barrel is off the centerline axis of the stock, causes the recoiling gun to move slightly outward in the direction of the barrel. This is 'corrected' by the 'convergence'. If you doubt this, take a set of sxs barrels that you know to have a good POI for you and set them on a solid surface, point the rib at a target, then look down each bore. They will 'converge' very close in. When you shoot that particular gun, you'll find it hits on point of aim regardless of distance.
So, verifying POI can be done at any distance. It is typically done at 16yds only when trying to calculate 'adjustments'. So, for the average guy just trying to see if your gun hits on for you, shoot it at the expected distance the gun/barrel will be used, IMO. I leave the "proper" POI check distance for when adjustments are known to be needed based on the test at functional distances.
