The reason I ask this is that you are using a cupped adjuster instead of a ball adjuster.
Also did you plug the oil holes in the shaft since it does not need to be full of oil because the oil is going around the inside of the rocker arm?

I had a similar thought about the shaft being full of oil, but could not convince myself that there was a downside to keeping oil in the shaft.
