Just galumping back
I don't know how many times I used the word visual in my book. I would say zero times, or close to it, because a visual is something you can actual see/capture with your eyes, not something you must imagine or visualize.
Thanks for responding. I had a hunch a quarters book wouldn't use the term.
You seem to have some confusion about a visual. CTE visuals are quite easy to see. In fact they're much easier for me to use than a 3/16 quarters alignment for example.
