Knight compiled a list of factors which control or influence the day-to-day behavior of many freshwater and saltwater fish.
As Knight's research progressed, he found that rather than just tides themselves, the relationship of the moon and sun's positions relative to each other may be the determining factor.
"...anglers have found that it is a guide to the best fishing of each day, and the quality of their sport has improved..."[4] Using these tables, a fisherman and a hunter can tell when the moon is directly underfoot or overhead.
Inconsistencies abound due to the complex nature of the astrophysics computations and overlooked associated anomalies-checking that are required to produce useful results.
Moon transits which do not occur for more than a day, or associated times being off more than a few minutes are indications of a fundamental issue for a given position and should be suspect.
