Yes and I really hate to say I following your discussion. I am color challenged so like chem geek I use the acid base drops to help me zero in on the pH. I do not use the acid base demand test to make actual changes to the pH in the pool knowing that ALK will affect the needed amount of acid. I am with water bear about pH meters. I still occasionally have to use one at work but try to use color indicators as much as possible. I understand the theory but know real world results are what count. My chemistry knowledge is mainly biochemistry so I do understand real world buffers. You should try adding protein buffers into the equation.
