Graham Phantom damping fluid level.

Bob Graham says to use enough fluid to bring the level up to the top of the square profile machined on the bearing cap. The square is only about 1/4" in length. My question is, What level works best for you in relationship to this "square" profile?

I have tried only 3 different levels of fluid in my setup (maximum level to top of square, almost no fluid at all, & to the bottom of the square) but can't seem to obtain optimum results so I'm wondering what others use, although I guess it's really cartridge dependent. Is the fluid level super sensitive? FWIW I'm using a Koetsu RSP.

Well,since I got my new Phantom yesterday(it is still in the sealed box)if there actually is a new bearing cap,I'm a happy fellow....Truthfully I am so happy to obtain the arm that I would have been happy with the original cap my friend has,on his arm.
BTW,I re-checked the fluid levels on my friend's Phantom,yesterday,at his request.He has made some system changes,and wanted me to re-voice his sound,using vta/vtf/fluid.We found that as of now,the fluid is at the bottom of the squared off bearing part.This is on "his" system,so it should vary.
Best.
