Hello,
With regards to the attached, there is an issue with the "Largest Contentful Paint (LCP) image subparts" description on CrUX Vis reports.

Here is the paragraph users see:

<p><a href="https://developers.chrome.com/docs/crux/methodology/metrics#lcp-image-subparts" target="_blank">Largest Contentful Paint (LCP) image subparts</a> help
          identify likely causes of slow image LCPs. They break the LCP time
          into four parts:
          &lt;ul&gt;
            &lt;li&gt;&lt;strong&gt;Time to first byte&lt;/strong&gt;: The time from when the user
                initiates loading the page until the browser receives the first
                byte of the HTML document response.&lt;/li&gt;
            &lt;li&gt;&lt;strong&gt;Resource load delay&lt;/strong&gt;: The time between TTFB and
                when the browser starts loading the LCP resource.&lt;/li&gt;
            &lt;li&gt;&lt;strong&gt;Resource load duration&lt;/strong&gt;: The duration of time it
                takes to load the LCP resource itself.&lt;/li&gt;
            &lt;li&gt;&lt;strong&gt;Element render delay&lt;/strong&gt;: The time between when the
                LCP resource finishes loading and the LCP element rendering fully.&lt;/li&gt;
          &lt;/ul&gt;
          LCP image subparts data  is only available for image LCPs (excluding videos).

          elements for your site.</p>
