That's very interesting.

When I saw the post, I Googled Graphene, because I am just interested in its unusual properties, and I thought I remembered there was something odd about its conductivity. The Wikipedia page is a little dense unless you're a physical chemist. I am a biologist with a basic science background, but I need to read it again and think about it. It seems there are two physical states of graphene, in one of which it is even more conductive than silver. In the other state, not so conductive. What triggers conversion between one state and another is where my ignorance lies. I got the impression that it only depends on the physical orientation of the lattice, which in a fluid medium such as a paste might be hard to control. You seem to have conducted two experiments where it was not conductive. Did you do anything to prove to yourself that it nevertheless enhances conductivity when used deliberately as a contact enhancer? Meantime, I have measured the resistance of the Walker Audio silver paste, and it seems to me if you just stick two ohmmeter probes in the paste, it did not conduct super well.
