Help me understand this result. First byte at 6.1s and first line item TTFB at 1.9s?

The page-level first byte time is for the first byte of actual HTML content so the 302 redirect time + the time for the page that it was redirected to. Looks like an interesting case for repeat view where the base HTML is cacheable though. For the first view I assume there's an HTML request right after the redirect and the first byte time is the point where that completes.

In this case it should be ~2.8s since the page that was redirected to is already in cache.
