Yes, I have. I have had Coors light with a reading of 4.4 in most accounts and suddenly found a starting PH of coors light at 3.45 in one account which would mean it had more acid than normal. After cleaning it read 4.3. I am finding older lines that are cleaned monthly instead of every two weeks have these variations. Anyone finding these variations?
I only calibrate once a month, the exact number is not as important and knowing that the PH is in the range it should be. I don't check the rinse water because it will really vary from account to account depending on the water supply.
