🎯 The key idea

👉 Green speed (in seconds) is the time a bowl takes to slow down and stop

NOT how fast it initially travels.

🧠 Why a 20‑second green is faster

✅ On a “fast” green (e.g. 20 seconds)

• The surface has low friction
• The bowl:
  • Slows down very gradually
  • Keeps rolling for longer
• So it takes more time before it stops

👉 Result: longer time = higher seconds = faster green

❌ On a “slow” green (e.g. 10 seconds)

• The surface has higher friction (often called a “heavy” green)
• The bowl:
  • Loses speed quickly
  • Stops sooner
• So it takes less time to stop

👉 Result: shorter time = lower seconds = slower green

⚖️ Simple analogy (makes it click)

Think of rolling a ball on two surfaces:

• Ice (fast surface)
  → Ball rolls for a long time
  → Takes longer to stop ✅
• Carpet (slow surface)
  → Ball stops quickly
  → Takes less time ✅

📐 Why this happens (physics in plain English)

• The ramp always gives the same starting speed
• After that, everything is about friction

From physics:

• Less friction → slower deceleration → longer stopping time
• More friction → faster deceleration → shorter stopping time

👉 That’s why on a fast surface the bowl doesn’t slow down as quickly and takes longer to stop.

Golfers measure green speed the other way round, with a Stimpmeter: there, a higher number means a faster green.

⚠️ Why it feels backwards

Normally we think:

• Faster = less time

But in bowls:

• You’re measuring how long the bowl keeps rolling, not how fast it starts

So:

• Fast green = bowl keeps going → more seconds
• Slow green = bowl dies quickly → fewer seconds

📊 Typical Green Speed ranges

• 9–11 sec → slow / heavy green
• 12–14 sec → average / good
• 15–19 sec+ → very fast green

🎯 How green speed affects your delivery

On a 20‑second (fast) green

• Use less effort
• Bowl travels further with gentle delivery
• Needs wider draw (more curve)

On a 10‑second (slow) green

• Use more effort
• Bowl loses pace quickly
• Needs straighter line

✅ One‑line summary

👉 In short, the higher the green speed in seconds, the faster the green. A higher seconds reading means a faster green because the bowl takes longer to lose its speed and come to rest, not because it started faster.
