I'm not really sure if there is any definite "signal" that the slurry is broken down; only that by the time it gets thick, it should be. Again, I'll let Jim confirm that.

First point: I tend to make my slurry without washing, but I haven't made a real comparison of both ways. I'll work on that this weekend. But since I get good results without it, I don't know that it's critical one way or another.

Second point: Yeah, that's it. The real signal is that keenness of the blade stops improving at a certain point, meaning the particles have lost their faster honing power. The visual cues, darkness and increasing thickness, are kind of coincidental but, since they're much easier to check for a new honer than keenness tests like HHT/AHT/TPT, I recommended them in the guide.
