Add some more lists, I’m slowly ramping up my blocking and sit a little higher than you in terms of %. I see a big spike in blocking when other users are around - obviously it depends heavily on where you go. Are you using an ad blocker on your device too?

It won't change much on a desktop device if you're already running things like uBlock Origin. But on mobile, where your options are a bit more limited, it can make a huge difference.

Right now I'm sitting around 68% blocked queries with two Smartphones connected to my Pihole.
