Very neat. I built a virtually identical internal tool for Blockmetry. A couple of tips from experience:

1. Add other browse extensions, and you'll see a big difference between their effects. Defaults matter a lot in this space.

2. Compare mobile vs desktop. Getting mobile emulation to be good enough is a bit of work, but worth it IMO.

Based on internal usage, the typical web page will load 35-45% faster with uBlock Origin installed.

My email address is my profile if you want to compare notes or whatnot.
