this is much better and cleaner! The tools will actually work well now with the
data.

I would suggest using the histogram_suffix structure to make this section
shorter and less error prone.

You can specify "ChromeStart", "LaunchFromDiagnostics" and
"LaunchFromPreferences" as your suffixes.

(not the affix example so you can keep the names the same). 
This will make this list much shorter and easier to add to.

Done.
