I’d be interested, over the last few years I’ve been trying to quantify effective boule, I had a go at creating a simple tool, with some simple rules for quantifying effectiveness. https://petanque-live-analysis-wpuktfvvnzfaaw54cjknbr.streamlit.app For each boule ask: 1. Did the boule improve our situation? • Yes → Effective • No → Go to Question 2 2. Did the boule make the opposition play? • Yes → Effective • No → Go to Question 3 3. Did the boule create a significant tactical advantage? • Yes → Effective • No → Non-Effective Observer's Golden Rule "Has this boule forced the opposition to reconsider or change their next action?” If YES → Effective Boule If NO → Non-Effective Boule
