Many astrologers who use classical astrology methods analyze the almutens of the 12 house cusps. Some astrologers use an equal house system but they prefer the chart wheel to display house cusp lines to the Asc and MC only. In earlier versions of Sirius the astrologer could select the Equal House System to get the desire almuten calculations but the chart wheel would show the 10th house cusp drawn to the point 90 degrees from the Asc rather than to the MC. An option has been added to have the house cusp line drawn to the MC and IC rather than the 10th house according to the equal house system and all calculations, including almuten calculations, are based on equal houses.
