I assume that without the tip you dont get an air poocket like you do with the tip thus you are using more reagent and throwing off the results. I have done Alk tests on the same water sample doing both with & without and i got different results. If i remember correctly my Alk with the tip was around 124 & with the tip it was 214.
I could try again just to see and use my crappy API as a comparison to see?
