Compare bytes document complete vs fully loaded

Analysis
1

I am able to find total bytes in no problem, but can I get that total at document complete and fully loaded. WPT summaries display them, but I can not figure out how to query those totals here.

I am thinking that reviewing this data might help quantify how much work is being done to optimize for critical render path.

Please let me know your thoughts?

You could add up the size of all the requests that start AFTER doc complete. The time the request starts is in the startedDateTime column BUT the granularity is in seconds (not milliseconds) so this will only provide an estimate.
