Yeah that’s pretty much it. To reference why
@Charlaquin has said they don’t like this methodology; the lock, the picker, and other surrounding circumstances, are like the “quantum ogre”.
In both this case and the case of the 4e “quantum ogre”, the “quantum” nature of the thing is false, it’s just that the mechanic isn’t meant to be physics. In 4e, the ogre is the same ogre, it just uses different mechanics in a different context.
In one-attempt resolution, the dice help determine part of the narrative circumstance. In other words, a 2 isn’t “objectively not the best one’s character could have done”, it’s just that your character’s best is being determined in a way that some folks have trouble internalizing and having satisfying gameplay with.
