For your finisher the thuri would usually be considered higher than the coticule and equivalent to the c12 or charnley. Just seems you are doing the same thing twice a lot. Do you have a 8 and 12 synthetic and magnification. If so do some scratch pattern testing and try to find what your stones are equivalent to as with naturals each stone is ymmv
Testing the scratch pattern sounds like a good idea. I've heard the coticule described as 8K, 10K, and 12K. Some professional honers go from the 8K synthetic to the coticule for finishing. My impression--only an impression--is that one of my coticules is fairly close to the Dragon's Tongue (8K), and the other closer to the Charnley Forest, Thuringian, or Chinese or Welsh 12K.

I gave up on the synthetics a while back. Kept getting metal chips embedded in the stone and putting nicks in the edge. But they could be useful for basic comparison.
