Come on. Are we now talking about degrees of quantum? As a theoretical physicist I can find this a bit amusing, but I sort of fail to see the practical relevance to try to introduce a measure of "quantumness" in RPG.
Not to sass your point though. The fact that the actions of the character more strongly affects the probability of a random events in different ways is really interesting. I want to point out that in trad you can also affect the encounter rate by various means dependent on system (Making noise being a big one, not being careful with your light sources is another in ShadowDark). But I really think it do not help the understanding to try to entangle the discussion about this with the term "quantum", that already has a pretty well defined meaning in RPG context.
