A Relationship Signature Is Not The Same As A Simple Compatibility Score
A compatibility score can flatten two charts into one number. A relationship signature is more useful when it shows which repeated signal leads the comparison. The same pair can show ease, pressure, attraction indicators, and long-term structure at once, but usually one pattern is more repeated than the others.
Why Repetition Matters More Than One Dramatic Aspect
A single intense contact can be meaningful, but it should not control the whole reading by itself. This tool looks for repeated signals across aspects, overlays, Nodes, Saturn, Juno, and attraction indicators. When both birth times are known, it also uses the traditional rulers of each person's eighth house as a small context layer without counting the same aspect twice. When several chart factors point to the same theme, the relationship signature becomes clearer and less dependent on one dramatic contact.
How To Use This Result Beside Synastry
Use the relationship signature as the headline, then open the full synastry chart for the detailed evidence. The signature tells you which repeated pattern leads the comparison. The synastry result explains the exact contacts behind that headline.
