Capacity Score & Invert Rule

The final Capacity score brings together Performance and Resource into a single number (0–100). An optional Invert rule can flip the meaning for functional malefics.

Overview

Capacity is the single number that summarises a planet's overall ability to deliver results in a chart. It blends two components:

• Performance — How the planet functions in this specific chart (house placement, lordship connections, star lord quality).
• Resource — The planet's inherent dignity (sign placement, special positions, afflictions).

After computing the Capacity score, the system checks whether the Invert rule applies. If it does, the score is flipped to reflect the planet's true effective delivery.

The Capacity Formula

Performance (0–100) contributes up to 70 points. Resource (0–100) contributes up to 30 points.

Notice how Performance dominates. A planet with high Performance but low Resource (90/40 = 75) scores much higher than one with equal moderate scores (50/70 = 56). This is intentional — chart-specific behaviour matters more than inherent dignity.

---

Why 70/30?

Performance (70%) measures how the planet functions in this specific chart. It accounts for house placement, lordship connections, and the star lord's quality. This is chart-specific and the most important factor in predicting results.

Resource (30%) measures the planet's inherent dignity — its sign placement, special positions like Vargottama or exaltation, and any afflictions like combustion or war. This is more universal and supplementary.

The 70/30 split ensures that a planet well-placed in the chart's house structure always outranks a planet that merely sits in a strong sign but has poor house connections.

The Invert Rule

For certain planets, a low Capacity score actually means good results (and vice versa). This happens when a planet is a functional malefic and has reduced light.

Invert Condition — both must be true:

1. Planet is a Functional Malefic for the ascendant
2. Planet's Light < 100 (retrograde or disrupted)

If both conditions are met:

The formula uses 200 (not 100) because it mirrors the score around the midpoint. A Capacity of 40 becomes 160, a Capacity of 80 becomes 120 — the lower the original score, the higher the inverted result.

---

Why Invert?

When a functional malefic planet is retrograde (Light < 100), its ability to do harm is reduced. A malefic with low capacity (normally bad) becomes beneficial when inverted.

Example: Saturn is a Functional Malefic for Aries ascendant. Suppose Saturn has Capacity = 46 and Light = 30.

• Invert applies (FM + Light < 100)
• Inverted = 200 − 46 = 154
• Display: 46/154*
• The * asterisk indicates inversion was applied

Saturn's low capacity (46) would normally mean weak results. But because Saturn is a malefic whose directional energy is disrupted, that weakness actually works in the native's favour — the planet cannot deliver its harmful agenda effectively. The inverted score (154) reflects this beneficial outcome.

---

Invert — When It Does NOT Apply

• Functional Benefics: NEVER inverted, even if retrograde. A benefic with reduced light simply delivers less good — it does not flip to harmful.
• Light = 100: NOT inverted, even if the planet is a functional malefic. When a planet has full directional energy, it delivers its malefic nature fully — no disruption means no inversion.

The following table shows how inversion applies for each planet in the sample chart (3001-02 M, 14-Mar-1987 09:48 AM, Pulivendula, AP — Aries Ascendant):

Note: Rahu and Ketu are classified directly via the Jupiter/Saturn Group system. Rahu is always in Saturn's group; Ketu is always in Jupiter's group.

Display Format

• Normal (no invert): Just show the Capacity score, e.g., 83
• Inverted: Show "score/invertedScore*", e.g., 46/154*
• The asterisk (*) only appears when inversion was actually applied

The dual display (46/154*) lets users see both the raw Capacity and the effective inverted score at a glance. The raw score shows what the planet's intrinsic scoring looked like; the inverted score shows the actual effective delivery after accounting for the malefic-with-reduced-light dynamic.

---

Rating Scale

For inverted scores, the inverted value is the "effective" score. A 154 inverted score means the planet effectively delivers at a very high level (despite appearing low in raw Capacity). Use the inverted value when judging the planet's real-world impact.
