 **Performance Score** is a rating from 0 to 100 that summarizes the perceived performance of your web application. Page loads and Interactions on your web application are scored based on their **Web Vitals**. Each **Web Vital** is given a rating from 0 to 100 through a [Log-Normal Distribution](https://www.desmos.com/calculator/o98tbeyt1t), which is then weighed and aggregated by page and overall for your entire web application.
 
+The overall **Performance Score** of your web application is the weighted average of your **Page Load** and **Interaction** scores. If your web application has far more Page Load scores than Interaction scores, your overall **Performance Score** will be biased towards Page Loads, and vice versa. An equal number of Page Load and Interaction scores produces an overall **Performance Score** comprised of a 50/50 average.

 A **Page Load Performance Score** is comprised of up to 4 individual **Web Vital** components found on each event. The default weights and rating thresholds for each **Web Vital** can be found in the table below.
