An experienced CTE player can see the CB last but yet at the same time peripherally see the OB relationship to the CB. In other words, both CB and OB can be viewed together.
It does not have to be one or the other.
That is not in pro books, so it must be ca ca.....
I am glad that I have learned to think outside of the box.

I would add that an experienced player sees both balls and the pocket all together, and that is no secret. That feedback is necessary to develop a feel for when a shot looks "on" reasonably quickly, and explains why back cuts tend to be more difficult. It is harder to see the pocket so it is harder to confirm that the shot will go.
I'm not sure anybody has said that when you look at one ball or the other you only see that ball. I think it is understood that one or other is in the periphery. That doesn't really address which ball should be looked at last. Personally I think if cb last worked better then 99% of players would be doing that... but they're not.
