We read two charts across four separate axes: Communication, Chemistry, Trust and Long-term. One can be strong while another is weak — and usually is. Averaging them would erase the one thing you actually need to know.
Each axis is read from its own planetary contacts. We show you which contacts produced each score — because a number whose source you cannot inspect is decoration, not a measurement.

They are not rivals; they answer different questions. Baby Astro computes both — knowing which one you need just makes it faster.
Two charts, compared
One chart, from the midpoints
A composite chart is a third chart derived from the midpoints of two natal charts — the chart of the relationship itself.
