Difference between the predicting technique in Astrology

If you just mark the lagna and planets in zodiac signs , then go straight to houses and give predictions, then it is traditional Astrology.
(Straight)
If you mark the lagna and planets in constellations , then go to constellations , further go to houses and give predictions, then it is stellar Astrology.
If you mark the lagna and planets in constellations and sub-constellations , then go to sub constellations , further go to constellations , then go to houses and give predictions, then it is fine level stellar Astrology.
(Just beating around the bush, finally the house only gives the results.)
