For example if you use gorhill's settings as you linked to earlier which do not enable fanboy's ultimate list (but do enable all the lists that the ultimate list contains) and then enabled the ultimate list on top of all the others, it would read as 0 out of x used.
I was *just* playing with it. Interestingly, enabling the Ultimate list gave me 97 new definitions. Strange, eh?
Seems like there's two ways of approaching things.
1) Use a couple huge lists from a couple providers, and reduce download times, and memory loading which could cause (mostly minor)performance reductions.
2) Use a bunch of lists(all of them?) for redundancy, so if one provider starts slacking off, or disappears completely, you're still covered by the others.
I'm kind of leaning towards option 2, but 1 might be better for very weak machines to keep all the performance possible.
Edit:
Switching between the Fanboy lists individually, and the Ultimate list; Ultimate at this time gives the most coverage. Enabling the other lists add three filters max to the Ultimate list, While Ultimate adds 97 to the other lists. I disabled Easylist and the separate Fanboy lists, and am using the Ultimate, with the other lists...
This should give maximum protection, while minimizing network use... FWIW... It's mostly theoretical I guess; kind of gilding the lily as it were :^D
Edit2:
Was looking over the screenshot, and noticed I still had EasyPrivacy enabled with four filters in use. Not much point in that, so I disabled that one also.
