I mean basically what is the spin of these projectiles when they leave the apparatus if they have no spin they would be affected like a knuckleball and may achieve a percentage of placements. But if they become entangled during the process they may produce a more accurate pattern. Wonder what would happen with entangled particles? I feel like maybe it has to do with the apparatus firing the electrons almost like a tool mark. Have lengths and tolerances been changed or has it always been the same apparatus?
