Practice playbook: drilling Key Origin Trebles without burning out

T20 dominance wins games — but treble-only drills go stale fast. Here's a 15-minute rotation that keeps players engaged and the hit rates climbing.

Key Origin Trebles (T20, T19, T18, T17) are the scoring backbone of the modern game. Drilling them is non-negotiable, but pointing a student at T20 for forty minutes burns them out by week three. The IDSL coach app's drill rotation handles this in a 15-minute block:

5 minutes — Open round on T20. No target count, no scoring. Just rhythm, stance, and follow-through. Coach watches mechanics, doesn't intervene.

5 minutes — 'Three of nine'. Three throws each at T20, T19, T18 — log every hit. Goal is three hits in nine darts on any single number. Two hits is normal; three is excellent.

5 minutes — Pressure round. Student picks one of the four trebles. They have nine darts to hit it three times. Miss the target and they restart — but with a positive trigger phrase first. This is where the focus-cue work shows up.

Log the totals to the coach app at the end of every session. Look for trend, not single-session noise. A student who's averaging two hits in nine on T20 in February and three hits in nine in May is on track. Don't reward best sessions — reward consistent ones.
