Abstract
Two or more sets of measurement data can be independently collected from causally related characteristics or elements. Such measurements can be synchronized with one another through the identification of a correct offset between their measurement data. An identification of the nature of the causal relationship between the measured characteristics can identify relevant ranges within which the aggregate values of one of the measurements can be obtained. As the offset between the measurements is adjusted, the aggregate values can change and a derivative, or other meaningful function based on the aggregate values can be calculated. The meaningful function, or subsequent functional result of it, can inform a range of offsets within which a local extreme value can be identified. The offset corresponding to such a local extreme value can be the correct offset.
