Age Group Development Concepts ★ ★ ★ ★ ★

🖼️ What

The competitive category based on a player's age (U10, U12, U14, U16, U18, Open).

📡 The Signal

Development stage and peer reference point. Playing up helps growth; staying in age group maximises ranking.

🎯 Why It Matters

Players compete primarily within their age group for rankings, but playing up provides development benefits.

⭐ Impact

2/5 — Contributing factor

📏 How to recognise it

Birth year determines age group eligibility for each competition year.

🚧 Common Mistake

Only competing in your own age group — playing up provides valuable experience against stronger, more mature players.

Seeding Development Concepts ★ ★ ★ ★ ★

🖼️ What

Pre-tournament ranking placement that prevents top players meeting in early rounds.

📡 The Signal

Recognition of ranking position. Being seeded is an advantage — easier early rounds and a protected draw.

🎯 Why It Matters

Seedings shape the draw and affect your path through a tournament.

⭐ Impact

2/5 — Contributing factor

📏 How to recognise it

Based on current ranking within the age group for that event.

🚧 Common Mistake
