In the analysis you may have found it strange that some planets are in a different house than you thought they were, or as they appear in the chart. This could be due to two reasons. The first is that the analysis you read used the House System of Porphyry, which I personally think is more correct because it covers the entire globe. The second is that these planets are in Metaichmium with the next House and therefore make a Conjunction with that House. The concept of Metaichmium was introduced by Alan Leo with whom I agree after personal experience, and he says that when a planet is close to the Beginning of the next House in less than 5 degrees, then it is considered that this planet belongs to the next House, because it forms Conjunction with the Beginning of this next House. Of course, when Metaichmio is used in predictive programs of Transits, Progresses, etc., then it is reduced to 1 degree.
We use the Porphyry house system because it covers the entire globe in contrast to the widespread but incomplete systems of Koch and Placidus.
