chainoften

Chainoften is a term used in theoretical discussions of sequential processes to denote a measure of periodicity and recurrence within a chain of events. The concept emerged in thought experiments and modelling discussions in the mid-2020s and has been referenced in studies of predictability in workflows, simulations, and narrative generation. It is not a standard term with a single formal definition, but rather a heuristic concept used to describe how regularly a sequence of steps tends to repeat.

Definition and intuition: Chainoften describes the tendency of a chain to repeat a particular sequence of steps. A high chainoften value suggests that once a transition occurs, the subsequent steps tend to follow a regular, recurring pattern across observations; a low value suggests more irregular or varied sequencing. In practice, the idea is to capture how strongly a process is constrained to follow a familiar path over time or across different runs.

Measurement and interpretation: In discussions, chainoften is often described qualitatively, and when quantified it is typically expressed as the fraction of transitions that are followed by the same next step across repeated trials. It is related to concepts such as determinism in a sequence, transition probability, and the degree of regularity in a process, but it remains a nonstandard metric without a universally accepted formula.

Applications and limitations: Chainoften has been used in speculative analyses of supply chains to distinguish routine from irregular operation, in algorithmic sequence generation to assess determinism, and in narrative design to study predictable plotting. A key limitation is the lack of consensus on definition and measurement, which can hinder comparability across studies.
