Thanks for that comment. I knew it was only a rough initial test, and didn't know about the inaccuracies you've highlighted.

So, the way I'd take it that it's not a very accurate test, but nonetheless useful as an eye opener to judge how somebody's adblocking posture is.

I wish there was a good (other) test around that's more reliable as well as easy for general people to follow.
