I decided to give it a shot. I grabbed another rocker and it was different than the one pictured above as it measured .230 (rocker to edge of adjuster) as it had no relief at all whereas the first one had a little. About 30 seconds with dremel and I was able to pick up .030 in depth and it is consistent with the first one pictured above, so it looks like i need to check them all so I can have some consistency.
