Yip i get what you mean but. When the secondary spot is centred in the the collimation scope. You can push and pull the collimation scope to get focus, But the push pull also rotates as well and this is when the dot goes back out of the bulls eye. I have see the links and i dont see any where that talks about rotation of the push pull on the collimations scope. All other stuff looks ok, spider, outer rings etc.
