Measured findings to investigate, ordered by audit score.
1. Largest Contentful Paint
Largest Contentful Paint marks the time at which the largest text or image is painted. [Learn more about the Largest Contentful Paint metric](https://developer.chrome.com/docs/lighthouse/performance/lighthouse-largest-contentful-paint/)
2. Forced reflow
A forced reflow occurs when JavaScript queries geometric properties (such as `offsetWidth`) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about [forced reflows](https://developer.chrome.com/docs/performance/insights/forced-reflow) and possible mitigations.
3. Network dependency tree
[Avoid chaining critical requests](https://developer.chrome.com/docs/performance/insights/network-dependency-tree) by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
4. Time to Interactive
Time to Interactive is the amount of time it takes for the page to become fully interactive. [Learn more about the Time to Interactive metric](https://developer.chrome.com/docs/lighthouse/performance/interactive/).
5. First Contentful Paint
First Contentful Paint marks the time at which the first text or image is painted. [Learn more about the First Contentful Paint metric](https://developer.chrome.com/docs/lighthouse/performance/first-contentful-paint/).
6. Speed Index
Speed Index shows how quickly the contents of a page are visibly populated. [Learn more about the Speed Index metric](https://developer.chrome.com/docs/lighthouse/performance/speed-index/).
7. Max Potential First Input Delay
The maximum potential First Input Delay that your users could experience is the duration of the longest task. [Learn more about the Maximum Potential First Input Delay metric](https://developer.chrome.com/docs/lighthouse/performance/lighthouse-max-potential-fid/).
8. Total Blocking Time
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds. [Learn more about the Total Blocking Time metric](https://developer.chrome.com/docs/lighthouse/performance/lighthouse-total-blocking-time/).

Battle scoring rules
The arena winner follows the verified ranking: internal link health first, then the published two-decimal quality score. Both sites need two agreeing standard observations. Browser performance, accessibility and SEO are complementary diagnostics and do not move the ranking or decide its winner. Page-only battles compare compatible rounds; performance differences up to five points draw, and equal round wins remain a tie. Missing measurements never count as zero. Browser audits do not certify accessibility. Saved results keep their measured evidence; start a rematch for a newer comparison.
