what about from the 5k naniwa going to the bbw then the yellow side with slight slurry?
Your problem is that you mix up synthetic hones and natural hones. Synthetic hones have an exact number that correlates with their particle size. That allows the user to put them in the correct working order. At least, when he stays within the same brand, but that's a story for another time. Natural hones don't have a grit number. That makes it difficult to put them in a progression. With Coticules and BBWs, the thickness of the slurry is directly connected to how sharp your edge will become
and to how efficient it cuts (in a reverse relation with the sharpness limit). Therefor, you can't put them in your progression without being able to know exactly how thick or thin you can make the slurry. Make it to thick and you will be working backwards. Make it too thin, and the whetstone will be too inefficient to catch on with the previous synthetic hone.
Or put in other words: most likely, your work on the yellow side with slight slurry after the BBW might as well be making your edge less sharp than it already was after the BBW. That is why we always advice to slowly dilute a slurry.
Somehow, you seem to think that the BBW is to be used before the Coticule. That is correct,
but only when we speak about the BBW
with slurry and the Coticule
wirth water. If you use both with slurry, it is, generally speaking, the other way round. Coticules with slurry: much faster and less sharp than a BBWs with the same slurry density.
Like I said earlier: you need to put a few hones away. I don't think anyone can or should be making that choice for you. You have to make it. Mixing both worlds, turns it into a rather complex process, and you need to be able to assess the sharpness of the blade well as you go along, to be successful.
Stick with the synthetics and follow the numbers: that is easy.
Stick with the Coticule and slowly dilute the slurry as you can see me doing in
this video: that is also easy.
But don't mix them up just yet. No one will be able to help you with something like that.
And finally, your easiest option of all:
Unicot.
