Yes that's correct, the uploaded image is right.Double check this one. CYA is a bit of an oddity, but there are no drops involved. You simply fill up the squeeze bottle with the solution and pool water, then you fill up the cylinder until the black dot at the bottom disappears.
You have a picture of the cylinder in one of your pictures and the line is between 50 and 60. Is that where the black dot disappeared? If so, round up and call your CYA 60.
