I for one would like to see what your real CYA level is so that you know how much water to drain. If you do not know your water table level, then there is some risk that your liner could lift (if vinyl lined), or your pool could float (if plaster) if it is too high.
Could you put your pool/equipment details in your sig. It helps us.
Here for comparison are the extended test kit directions for cya: http://www.troublefreepool.com/extended-test-kit-directions-t25081.html#p206397 Take a look at them and see if they suggest anything to you about your technique.
