Time's been short, so I've not posted on several questions about naturals.

Friables (thuri/escher & Jnats) are spoken of as having desireable properties because the grit breaks down into finer particles, giving a finer finish as the slurry gets worked.

So either this grit breaks down in a very few (10?) strokes, or there's a disconnect in the honing discussions on their use. '10, no more than 20 strokes' etc. Can the grit breakdown happen that fast, or do the short-strokers (not meaning disrespect - they get results) bypass the finer stages of particle breakdown because the stone is so fine to begin with? Would it not be better w/ a period (some number of strokes) applied to break down the grit further?

I'd appreciate your thoughts here.
