Opinion follows:
For a finisher once it is flat enough never lap it again.
Use the rubbing stone to help keep it flat enough..

If the shave is not smooth enough hone with lather and rinse well when done.

Use as light a touch as you can. Slow and deliberate.

Five/six stroke pairs only,,,, strop at least twice and if it still feels dull
give it five more strokes on the hone.

Pull strokes work...I have been astounded with the edge from
only a small coti slurry stone.

Coti slurry on canvas is often a good thing in moderation.
(a bit of slurry from any finisher on canvas can be good.)

Once a razor is shave ready sharp stick to the finisher hones
8K and finer or your natural finisher. Almost no shave related
dullness justifies more grinding....
