An increase of the average above 1 indicates a gradual progression into the rare-event regime, and is accompanied by a shortening of the intervals between each successive nanosecond of elapsed MD time. For the variable τ var approach, this transition is smoother and occurs at a higher reactive cycle compared to the constant approach. Factors i) and ii) introduced previously are minimized for longer, allowing for more extensive simulation of SEI growth within a given set of computational resources.
