If this is how you're measuring speed, then the adder I've got is 2.5 ticks - 1.5 for the first XNOR, carry is cut by default(I guess? I'm not entirely sure what you mean), 1 tick for the second XNOR. It's three wide though. But there is this little timing bug I found that makes it two ticks under certain circumstances: a repeater powering a piston will yield an output after 2 ticks instead of 2.5. That would make the first XNOR output after just one tick instead of 1.5. And now I just went and tested it with torches (to check that it was different) and it was the same as with a repeater. But using just redstone would yield an output after 1.5 ticks like expected. Weird :S Still, I guess that that makes pistons functionally one tick then doesn't it?
