Scores summarize, they do not decide
Compatibility scores can be useful when they summarize a complicated chart clearly. They become misleading when they pretend a relationship can be reduced to a single number. StarFable uses scores as a starting point for interpretation, not as a verdict.
The four categories are Romance, Communication, Chemistry, and Long-term Potential. Each one draws from different kinds of synastry contacts, with stronger emphasis on the planets most relevant to that category.
Aspect type matters
Trines and sextiles generally raise a category because they show smoother flow, support, or cooperation. Squares and oppositions usually lower a category because they add friction, tension, mismatch, or work. Conjunctions are handled more carefully because they intensify whatever planets are involved.
A conjunction between Venus and Mars may boost chemistry. A conjunction involving Saturn and the Moon may add seriousness but also emotional pressure. The same aspect type can mean different things depending on the planets.
Orb tightness changes strength
A tight aspect counts more strongly than a loose aspect. If two planets are almost exactly trine, that pattern is likely to be more noticeable than the same trine near the edge of the allowed orb.
StarFable weights aspect strength by orb so exact or near-exact contacts influence the score more. Wider aspects still matter, but they do not crowd out the clearest signals in the chart.
Planet significance changes the category
A Mercury-Mercury or Mercury-Moon contact matters strongly for Communication. Venus, Moon, and Jupiter contacts often matter for Romance. Venus-Mars and Mars contacts contribute to Chemistry. Saturn contacts often influence Long-term Potential because they describe time, responsibility, maturity, and commitment pressure.
This category weighting helps the score feel more like a relationship reading and less like a generic point system. The score tries to answer a human question: where does this connection have ease, and where does it ask for more skill?
Why the written interpretation matters more
A number can orient you, but the written interpretation explains the pattern. Two couples can both have a 7.5 overall score and still have very different stories. One may have warm emotional support and moderate chemistry. Another may have intense attraction and more difficult communication.
Use the score to see the shape of the chart quickly. Use the interpretation to understand what the chart is asking you to notice, practice, and discuss.
