# CHCA Player Selection (PS) Score — How It Is Calculated

The Player Selection (PS) score is a single number out of **100** that ranks
players for team selection **within their own age group**. It is built from
five categories.

| Category | Max | How it is measured |
|---|---:|---|
| District Trial Performance | 40 | Automatic, from designated district-trial results |
| Official Rating | 20 | Automatic, from a weighted rating |
| District Participation | 20 | Manual — admin confirms attendance at hosted events |
| Conduct & Discipline | 10 | Starts at 10, deducted per logged incident |
| Proof of Income | 10 | Band of the uploaded income document (−5 if none) |

Total is clamped to the 0–100 range.

## 1. District Trial Performance (40)

Each trial a player takes part in is scored out of 40 as three sub-factors,
then a player's final component score is the **average across all trials** they
played this season.

**Final Standing (20)** — standing is derived from points scored in the trial
crosstable (ties broken by higher average opponent rating).

| Final Standing | Points |
|---|---:|
| 1st–3rd | 20 |
| 4th–10th | 15 |
| 11th–20th | 10 |
| 21st–30th | 5 |
| 31st+ | 2 |

**Strength of Opposition (10)** — average rating of opponents faced in the trial.

| Avg Opponent Rating | Points |
|---|---:|
| 1800+ | 10 |
| 1600–1799 | 8 |
| 1400–1599 | 6 |
| 1200–1399 | 4 |
| Below 1200 | 2 |

**Number of Wins (10)** — win rate = wins ÷ games played in the trial.

| Win Rate | Points |
|---|---:|
| 80–100% | 10 |
| 60–79% | 8 |
| 40–59% | 6 |
| 20–39% | 4 |
| Below 20% | 2 |

*A tournament is only counted here after an admin flags it as a District Trial
(a checkbox on the tournament upload screen, or the trials list).*

## 2. Official Rating (20)

Uses a **weighted average rating**:

```
weighted = 0.60 × Standard + 0.30 × Rapid + 0.10 × Blitz
```

| Weighted Rating | Points |
|---|---:|
| 1800+ | 20 |
| 1600–1799 | 15 |
| 1400–1599 | 10 |
| 1200–1399 | 5 |
| Below 1200 | 2 |

## 3. District Participation (20)

`attendance % = events attended ÷ total events hosted this season`.

| Attendance % | Points |
|---|---:|
| 80–100% | 20 |
| 60–79% | 15 |
| 40–59% | 10 |
| Below 40% | 5 |

If no events have been hosted yet, this category scores 0.

## 4. Conduct & Discipline (10)

Everyone starts at **10**. Each logged incident deducts points; the score is
floored at 0.

| Incident | Deduction |
|---|---:|
| Minor Code of Conduct violation | −3 |
| Major misconduct at official events | −5 |
| Unpaid fines / fraudulent documentation | −10 |

## 5. Proof of Income (10)

Taken from the most recent uploaded proof-of-income document's band.

| Submission | Points |
|---|---:|
| SASSA confirmation / unemployed affidavit | 10 |
| Low-income band | 7 |
| Mid-income band | 4 |
| High-income band | 2 |
| No submission | −5 (penalty) |

## Worked examples

### Example A — Thandi (U14)

- Played 2 district trials.
  - Trial 1: finished 2nd (20), avg opponent 1520 (6), won 4 of 5 = 80% (10) → **36**
  - Trial 2: finished 7th (15), avg opponent 1610 (8), won 3 of 5 = 60% (8) → **31**
  - Trial component = (36 + 31) ÷ 2 = **33.5 / 40**
- Ratings: Std 1650, Rapid 1500, Blitz 1400 → weighted = 0.60·1650 + 0.30·1500 + 0.10·1400 = 990 + 450 + 140 = **1580** → 1400–1599 band → **10 / 20**
- Attended 4 of 5 events = 80% → **20 / 20**
- No discipline incidents → **10 / 10**
- Uploaded a low-income payslip → **7 / 10**

**Total = 33.5 + 10 + 20 + 10 + 7 = 80.5 / 100**

### Example B — Sipho (U16)

- One district trial: finished 15th (10), avg opponent 1300 (4), won 2 of 6 = 33% (4) → trial = **18 / 40**
- Ratings: Std 1420, Rapid 1380, Blitz 1300 → weighted = 852 + 414 + 130 = **1396** → 1200–1399 band → **5 / 20**
- Attended 2 of 5 events = 40% → **10 / 20**
- One major misconduct incident → 10 − 5 = **5 / 10**
- No income document uploaded → **−5 / 10**

**Total = 18 + 5 + 10 + 5 − 5 = 33 / 100**

### Example C — Lerato (U12), no trials yet

- No trials played → **0 / 40**
- Ratings: Std 1250, Rapid 1200, Blitz 1200 → weighted = 750 + 360 + 120 = **1230** → 1200–1399 → **5 / 20**
- Attended 5 of 5 events = 100% → **20 / 20**
- No incidents → **10 / 10**
- SASSA affidavit uploaded → **10 / 10**

**Total = 0 + 5 + 20 + 10 + 10 = 45 / 100**

*Scores recalculate automatically as trials are flagged, attendance is
confirmed, incidents are logged, and income documents are uploaded. Discipline
and income are stored as an auditable log/submission (never a hand-edited
balance), so the score is always reproducible.*
