Right about terms!! Ptolemy himself talked about previous Egyptian and Chaldean term systems, and then went on to modify yet another system of terms ("taken from an old book" ) into what became the Ptolemaic terms. Manilius (before Ptolemy) suggested yet another system of terms based on 1/2 degree sections of a sign via duodenary division (see Gould's introduction to the Astronomica) Then there were the terms of Astaurus (mentioned by al-Biruni), a system of Hindu terms (described in al-Biruni's "Elements") and then Lilly's reworking of Ptolemy's terms!
So we have (historically):
Chaldean-Egyptian-Manilius-Ptolemaic-Astaurus-Hindu-and reworked (Lilly) Ptolemaic systems of terms. And they are ALL different!
I gave up using term systems for any purpose, years ago: I use that most ancient system of planetary monomoiria (dating to early Hellenist times) which has always been the same and consistent, and includes ALL the planets (does not exclude the luminaries, which all systems of terms do: note that when using any system of terms one is mechanically discriminating against the Sun and the Moon in arriving at essential dignity: Sun and Moon can score essential dignity by domicile, exaltation, triplicity and face but are automatically excluded from scoring essential dignity by term: puts Sun and Moon at a 20% disadvantage to the other 5 planets in scoring essential dignity and increases the potential for Sun and Moon to be peregrine by 20% over the other 5 planets!! Using monomoiria instead of terms, eliminates this mechanical essential-dignity bias against Sun and Moon...but of course no authority has "authorized" use of monomoiria instead of term systems over the past 1500 years, so it would not be "...traditional..."to do so
