Talked with @Krinkle today and we both feels that https://grafana.wikimedia.org/dashboard/db/webpagetest contains too much information. Lets clean it up and focus on finding regressions:

• focus on SpeedIndex and start render (that's what WPT does best)
• default should be the page where it's easiest to find a regression (change blank to Facebook)
• cleanup the areas that displays size, lets make them simpler and easier to find regression
