Is the hypothesis accurate?
In the analog, yes. A complete individual state fixes one first-exit time. Withholding the remainder recovers a waiting-time spread. Revealing more of the true remainder shrinks both variance and error to the true instant. Dummy variables do not. That is exactly Einstein’s kinetic-theory relation, made numerical.
It does not show that a real nucleus, or nature, is built this way. Rank-1 is supported as a schema. Nature still needs a characterized analog whose background you can actually read.
