Rocker arm wear pattern

I took pictures of the roller travel at 1/2, full and closed. The lash cap helped a bit, it seems to be centered at zero lift, it just moves forward as it opens the valve. They are 60 thou lash caps I believe, I just borrowed one somebody had lying around.

Sorry if its hard to see, I had a really hard time taking clear pictures for some reason. Also I had to mark the travel on the lash cap as it was hard to see.
