As I understand the UP, it's a statistical statement about an ensemble of observations, say for position and momentum of identical particles. It says nothing about the result of events, say for the position and momentum of a single particle or event. Doing some arithmetic to get the time-energy form of the UP does not change this reality. As a result, your description of what happens to a single particle, virtual or not, is not intelligible. Please try again.
