No. With practice, it is fairly easy to do.
With the sun at your back, fill the tube to 100, glance for the dot with the tube at waist level, if you see the dot, fill to 90, glance, repeat.
After you get a value, pour the sample back into the dropper bottle, and do it again. Average out several tests rounding up to the nearest whole 10.
Take care.

Ah, I didn't realize you could continue to redo the test with the same sample. I understand the test is subjective, but I seem to be at the extreme with the varying results I'm getting!

Even better is to get another person to do the test along with you. Different eyes.
Be sure to 'glance'. Staring at the dot will trick your eyes into seeing it.

There's no shame in repeating the CYA test a dozen times until you get close readings 3 or 4 times in a row.
If you the OCD type, there's also a CYA standard.... you mix it up and figure out a test procedure that gives you the right reading. Then do exactly the same thing with the pool water sample.
