How matches are scored
Two different calculations sit behind the people you see. Type harmony on My Chart compares your chart to a glyph, which is a pattern and carries no pillars. A pair reading on the Match screen compares two real charts, branches and all. They are not the same arithmetic, and the difference is the first thing below.
For the sections these numbers appear in, see people & matches.
How we calculate type harmony
- Compare your chart to each glyph on four things it can know about a glyph: how your day element and its element meet, how the two strengths sit together, drive against drive, and rhythm against rhythm. Then one more — whether that glyph's element is on your helpful or your caution list. No LLM ranking.
- Animal branches are not in this one. A glyph is an element, a strength, a drive, and a rhythm; it carries no pillars, so there are no branches to clash or combine. That is the difference between this and a real pair reading on the Match screen, which does read branches.
- Score separately per framing context (romance vs work uses different weights).
- Surface best and worst ends for scanability — not a verdict about specific people.
How a pair reading is scored
This is the other calculation — the one behind a pair reading on the Match screen, where two real charts meet. Unlike type harmony above, it reads branches, so clashes and combinations between the two sets of pillars count.
Five things are compared, and each finding they produce carries a direction and a confidence:
- Core chemistry — how the two day elements meet.
- Everyday dynamics— how the pillars' branches interact, pillar by pillar.
- Element support — whether your helpful and caution lists overlap or cut across each other, and whether one chart actually holds what the other is missing. See below.
- Drive fit — whether the two charts want similar things.
- Pace & rhythm — whether one leans active where the other leans quiet.
Each finding counts +1 if it leans supportive, −1 if it leans effortful, multiplied by how confident it is — 3 for high, 2 for medium, 1 for low. Add those up, multiply by four, and add fifty. That is the score, and it is why fifty means “nothing pulling either way” rather than “average”.
The “How the score adds up” panel on the reading is that same arithmetic, one bar per component. It is a receipt, not a second opinion.
When one of you has what the other lacks
This is the part of a pairing that traditional practice treats as the heart of it, and it is the reason two people with very different charts can steady each other.
Your helpful elements are what your chart is short of. Roughly one person in four holds none at all of an element their own chart says would settle them. So the reading asks a second question about elements: does the other chart actually carry it? When one of you holds none of something and the other holds a lot, that counts toward the score.
The same question runs the other way. If one chart is heavy in an element the other already finds effortful, that counts against — and both can be true in the same pairing. Someone can fill a real gap for you and bring a lot of what tires you, at once.
Mutual counts for more than one-way.Both charts covering each other's gaps is a different pairing from one person doing all the filling, and the reading says which it is. It does not say who — the calculation is deliberately the same read from either side, so the same pair never gives two different answers depending on who opened it.
Why Love and Work give different numbers
The five tabs do not run five separate readings. They score the same findings with different weights, because what matters between two people depends on what they are to each other.
- Overall weights everything equally — it is the plain, unweighted score.
- Love leans hardest on the day branches, the pillar traditionally read for a partner, and on rhythm.
- Work leans on drive and element support, and discounts branch interactions.
- Family leans on the year and month branches — the household and upbringing layers.
- Friends leans on rhythm and drive, and cares least about the year branch.
So a pair can be steadier at work than in romance from one identical set of findings. Switching tabs re-weights the bars as well as the number, which is what lets you see which component the difference came from.
