1. In a liquid product facility that periodically performs a physical to book balance reconciliation process, a method of trending the variance between volume of liquid product as recorded in a book balance and a measured volume of physical liquid product in a thank the method comprising:

  • collecting three or more volume book balances of the liquid product in a manifold set of tanks at three or more physical to book balance reconciliation times, the three or more volume book balances generated using a reconciliation system capable of automatically performing a physical product to book balance reconciliation process regardless of current delivery, dispensing, or both, of the liquid product;

    collecting, by the reconciliation system, three or more physical volumes of the liquid product in the manifold set of tanks, which corresponds to an actual volume of liquid product within the manifold set at three or more physical to book balance reconciliation times;

    automatically calculating, by the reconciliation system, variance data indicative of a difference between each of the three or more physical volumes and the three or more volume book balances at the corresponding physical to book balance reconciliation times; and

    storing the variance data for showing a pattern-like relationship of a loss, gain, or both, of liquid product over a period of time.
