Deterministic queries under the effect of common characteristics of time courses. In (a) both time courses are in the result set of the deterministic query interpretation. For (b), (c) and (d) the red time course is not included in the result set. In (b) a phase shift has moved the red time course out of the query's scope. In (c) an outlier prevents the red time course from being included. In (d) a variation in the speed at which values are taken prevents the red time course from matching the deterministic query interpretation. See the Results section on how deterministic timebox queries are evaluated.
