Frequently Asked Questions
Everything you need to know about using this application.
What is the formula used for this decathlon calculator?
This calculator utilizes the official IAAF (World Athletics) scoring tables for combined events. The formula calculates points based on performance: for running events, points are determined by (a * (b - T)^c), while jumping and throwing events use (a * (M - b)^c). Because of this, the scoring system is non-linear. The more performance improves, the more points are awarded for each increment, accurately reflecting the difficulty of higher-level athleticism in track and field.
Does this tool save my decathlon scores?
For security and privacy reasons, this application operates entirely in your browser's memory without using cookies, local storage, or databases. Your input data is cleared immediately when you refresh or close the page. This design ensures total data privacy as no information ever leaves your device or is stored on a server. If you need to keep your scores, please use the provided print function to export your current calculations.
Which track and field events are included?
The application includes all 10 standard events required for a men's Decathlon: 100 meters, long jump, shot put, high jump, 400 meters, 110-meter hurdles, discus throw, pole vault, javelin throw, and the 1500 meters. Each input field is tailored to the specific units of measurement required for that event, such as seconds for sprints and meters for throws and jumps, ensuring seamless data entry and accurate point generation.
Can I use this on mobile devices?
Yes, the interface is fully responsive and optimized for mobile devices, tablets, and desktop computers. The grid layout automatically adjusts to fit your screen, making it easy to input performance times and distances track-side or at the gym. We utilize a modern, touch-friendly UI design that ensures buttons and input fields are easy to tap, providing a native-app-like experience directly within your mobile web browser.
